17 DRIVER => [ 'Generic', { user1 => '123' } ],
18 );

26 }
28
30 CGI::Application::Plugin::Authentication adds the ability to
31 authenticate users in your CGI::Application modules. It imports one
32 method called 'authen' into your CGI::Application module. Through the
33 authen method you can call all the methods of the
34 CGI::Application::Plugin::Authentication plugin.
35 There are two main decisions that you need to make when using this
37 module. How will the usernames and password be verified (i.e. from a
38 database, LDAP, etc...), and how can we keep the knowledge that a user
39 has already logged in persistent, so that they will not have to enter
40 their credentials again on the next request (i.e. how do we 'Store' the
41 authentication information across requests).
42 Choosing a Driver
44 There are three drivers that are included with the distribution. Also,
45 there is built in support for all of the Authen::Simple modules (search
46 CPAN for Authen::Simple for more information). This should be enough
47 to cover everyone's needs.
48 If you need to authenticate against a source that is not provided, you
50 can use the Generic driver which will accept either a hash of
51 username/password pairs, or an array of arrays of credentials, or a
52 subroutine reference that can verify the credentials. So through the
53 Generic driver you should be able to write your own verification
54 system. There is also a Dummy driver, which blindly accepts any
55 credentials (useful for testing). See the
56 CGI::Application::Plugin::Authentication::Driver::Generic,
57 CGI::Application::Plugin::Authentication::Driver::DBI and,
58 CGI::Application::Plugin::Authentication::Driver::Dummy docs for more
59 information on how to use these drivers. And see the Authen::Simple
60 suite of modules for information on those drivers.
61 Choosing a Store
63 The Store modules keep information about the authentication status of
64 the user persistent across multiple requests. The information that is
65 stored in the store include the username, and the expiry time of the
66 login. There are two Store modules included with this distribution. A
67 Session based store, and a Cookie based store. If your application is
68 already using Sessions (through the CGI::Application::Plugin::Session
69 module), then I would recommend that you use the Session store for
70 authentication. If you are not using the Session plugin, then you can
71 use the Cookie store. The Cookie store keeps all the authentication in
72 a cookie, which contains a checksum to ensure that users can not change
73 the information.
74 If you do not specify which Store module you wish to use, the plugin
76 will try to determine the best one for you.
77 Login page
79 The Authentication plugin comes with a default login page that can be
80 used if you do not want to create a custom login page. This login form
81 will automatically be used if you do not provide either a LOGIN_URL or
82 LOGIN_RUNMODE parameter in the configuration. If you plan to create
83 your own login page, I would recommend that you start with the HTML
84 code for the default login page, so that your login page will contain
85 the correct form fields and hidden fields.
86 Ticket based authentication
88 This Authentication plugin can handle ticket based authentication
89 systems as well. All that is required of you is to write a Store
90 module that can understand the contents of the ticket. The
91 Authentication plugin will require at least the 'username' to be
92 retrieved from the ticket. A Ticket based authentication scheme will
93 not need a Driver module at all, since the actual verification of
94 credentials is done by an external authentication system, possibly even
95 on a different host. You will need to specify the location of the
96 login page using the LOGIN_URL configuration variable, and
97 unauthenticated users will automatically be redirected to your ticket
98 authentication login page.
99
101 authen
102 This is the only method exported from this module. Everything is
103 controlled through this method call, which will return a
104 CGI::Application::Plugin::Authentication object, or just the class name
105 if called as a class method. When using the plugin, you will always
106 first call $self->authen or __PACKAGE__->authen and then the method you
107 wish to invoke. For example:
108 __PACKAGE__->authen->config(
110 LOGIN_RUNMODE => 'login',
111 );
112 - or -
114 $self->authen->protected_runmodes(qw(one two));
116
118 config
119 This method is used to configure the
120 CGI::Application::Plugin::Authentication module. It can be called as
121 an object method, or as a class method. Calling this function, will not
122 itself generate cookies or session ids.
123 The following parameters are accepted:
125 DRIVER
127 Here you can choose which authentication module(s) you want to use
128 to perform the authentication. For simplicity, you can leave off
129 the CGI::Application::Plugin::Authentication::Driver:: part when
130 specifying the DRIVER name If this module requires extra
131 parameters, you can pass an array reference that contains as the
132 first parameter the name of the module, and the rest of the values
133 in the array will be considered options for the driver. You can
134 provide multiple drivers which will be used, in order, to check the
135 credentials until a valid response is received.
136 DRIVER => 'Dummy' # let anyone in regardless of the password
138 - or -
140 DRIVER => [ 'DBI',
142 DBH => $self->dbh,
143 TABLE => 'user',
144 CONSTRAINTS => {
145 'user.name' => '__CREDENTIAL_1__',
146 'MD5:user.password' => '__CREDENTIAL_2__'
147 },
148 ],
149 - or -
151 DRIVER => [
153 [ 'Generic', { user1 => '123' } ],
154 [ 'Generic', sub { my ($u, $p) = @_; is_prime($p) ? 1 : 0 } ]
155 ],
156 - or -
158 DRIVER => [ 'Authen::Simple::LDAP',
160 host => 'ldap.company.com',
161 basedn => 'ou=People,dc=company,dc=net'
162 ],
163 STORE
165 Here you can choose how we store the authenticated information
166 after a user has successfully logged in. We need to store the
167 username so that on the next request we can tell the user has
168 already logged in, and we do not have to present them with another
169 login form. If you do not provide the STORE option, then the
170 plugin will look to see if you are using the
171 CGI::Application::Plugin::Session module and based on that info use
172 either the Session module, or fall back on the Cookie module. If
173 the module requires extra parameters, you can pass an array
174 reference that contains as the first parameter the name of the
175 module, and the rest of the array should contain key value pairs of
176 options for this module. These storage modules generally live
177 under the CGI::Application::Plugin::Authentication::Store:: name-
178 space, and this part of the package name can be left off when
179 specifying the STORE parameter.
180 STORE => 'Session'
182 - or -
184 STORE => ['Cookie',
186 NAME => 'MYAuthCookie',
187 SECRET => 'FortyTwo',
188 EXPIRY => '1d',
189 ]
190 POST_LOGIN_RUNMODE
192 Here you can specify a runmode that the user will be redirected to
193 if they successfully login.
194 POST_LOGIN_RUNMODE => 'welcome'
196 POST_LOGIN_URL
198 Here you can specify a URL that the user will be redirected to if
199 they successfully login. If both POST_LOGIN_URL and
200 POST_LOGIN_RUNMODE are specified, then the latter will take
201 precedence.
202 POST_LOGIN_URL => 'http://example.com/start.cgi'
204 POST_LOGIN_CALLBACK
206 A code reference that is executed after login processing but before
207 POST_LOGIN_RUNMODE or redirecting to POST_LOGIN_URL. This is
208 normally a method in your CGI::Application application and as such
209 the CGI::Application object is passed as a parameter.
210 POST_LOGIN_CALLBACK => \&update_login_date
212 and later in your code:
214 sub update_login_date {
216 my $self = shift;
217 return unless($self->authen->is_authenticated);
219 ...
221 }
222 LOGIN_RUNMODE
224 Here you can specify a runmode that the user will be redirected to
225 if they need to login.
226 LOGIN_RUNMODE => 'login'
228 LOGIN_URL
230 If your login page is external to this module, then you can use
231 this option to specify a URL that the user will be redirected to
232 when they need to login. If both LOGIN_URL and LOGIN_RUNMODE are
233 specified, then the latter will take precedence.
234 LOGIN_URL => 'http://example.com/login.cgi'
236 LOGOUT_RUNMODE
238 Here you can specify a runmode that the user will be redirected to
239 if they ask to logout.
240 LOGOUT_RUNMODE => 'logout'
242 LOGOUT_URL
244 If your logout page is external to this module, then you can use
245 this option to specify a URL that the user will be redirected to
246 when they ask to logout. If both LOGOUT_URL and LOGOUT_RUNMODE are
247 specified, then the latter will take precedence.
248 LOGIN_URL => 'http://example.com/logout.html'
250 DETAINT_URL_REGEXP
252 This is a regular expression used to detaint URLs used in the login
253 form. By default it will be set to
254 ^([\w\_\%\?\&\;\-\/\@\.\+\$\=\#\:\!\*\"\'\(\)\,]+)$
256 This regular expression is based upon the document
258 http://www.w3.org/Addressing/URL/url-spec.txt. You could set it to
259 a more specific regular expression to limit the domains to which
260 users could be directed.
261 DETAINT_USERNAME_REGEXP
263 This is a regular expression used to detaint the username parameter
264 used in the login form. By default it will be set to
265 ^([\w\_]+)$
267 CREDENTIALS
269 Set this to the list of form fields where the user will type in
270 their username and password. By default this is set to
271 ['authen_username', 'authen_password']. The form field names
272 should be set to a value that you are not likely to use in any
273 other forms. This is important because this plugin will
274 automatically look for query parameters that match these values on
275 every request to see if a user is trying to log in. So if you use
276 the same parameter names on a user management page, you may
277 inadvertently perform a login when that was not intended. Most of
278 the Driver modules will return the first CREDENTIAL as the
279 username, so make sure that you list the username field first.
280 This option can be ignored if you use the built in login box
281 CREDENTIALS => 'authen_password'
283 - or -
285 CREDENTIALS => [ 'authen_username', 'authen_domain', 'authen_password' ]
287 LOGIN_SESSION_TIMEOUT
289 This option can be used to tell the system when to force the user
290 to re-authenticate. There are a few different possibilities that
291 can all be used concurrently:
292 IDLE_FOR
294 If this value is set, a re-authentication will be forced if the
295 user was idle for more then x amount of time.
296 EVERY
298 If this value is set, a re-authentication will be forced every
299 x amount of time.
300 CUSTOM
302 This value can be set to a subroutine reference that returns
303 true if the session should be timed out, and false if it is
304 still active. This can allow you to be very selective about
305 how the timeout system works. The authen object will be passed
306 in as the only parameter.
307 Time values are specified in seconds. You can also specify the time
309 by using a number with the following suffixes (m h d w), which
310 represent minutes, hours, days and weeks. The default is 0 which
311 means the login will never timeout.
312 Note that the login is also dependent on the type of STORE that is
314 used. If the Session store is used, and the session expires, then
315 the login will also automatically expire. The same goes for the
316 Cookie store.
317 For backwards compatibility, if you set LOGIN_SESSION_TIMEOUT to a
319 time value instead of a hashref, it will be treated as an IDLE_FOR
320 time out.
321 # force re-authentication if idle for more than 15 minutes
323 LOGIN_SESSION_TIMEOUT => '15m'
324 # Everyone must re-authentication if idle for more than 30 minutes
326 # also, everyone must re-authentication at least once a day
327 # and root must re-authentication if idle for more than 5 minutes
328 LOGIN_SESSION_TIMEOUT => {
329 IDLE_FOR => '30m',
330 EVERY => '1d',
331 CUSTOM => sub {
332 my $authen = shift;
333 return ($authen->username eq 'root' && (time() - $authen->last_access) > 300) ? 1 : 0;
334 }
335 }
336 RENDER_LOGIN
338 This value can be set to a subroutine reference that returns the
339 HTML of a login form. The subroutine reference overrides the
340 default call to login_box. The subroutine is normally a method in
341 your CGI::Application application and as such the CGI::Application
342 object is passed as the first parameter.
343 RENDER_LOGIN => \&login_form
345 and later in your code:
347 sub login_form {
349 my $self = shift;
350 ...
352 return $html
353 }
354 LOGIN_FORM
356 You can set this option to customize the login form that is created
357 when a user needs to be authenticated. If you wish to replace the
358 entire login form with a completely custom version, then just set
359 LOGIN_RUNMODE to point to your custom runmode.
360 All of the parameters listed below are optional, and a reasonable
362 default will be used if left blank:
363 DISPLAY_CLASS (default: Classic)
365 the class used to display the login form. The alternative is
366 "Basic" which aims for XHTML compliance and leaving style to
367 CSS. See CGI::Application::Plugin::Authentication::Display for
368 more details.
369 TITLE (default: Sign In)
371 the heading at the top of the login box
372 USERNAME_LABEL (default: User Name)
374 the label for the user name input
375 PASSWORD_LABEL (default: Password)
377 the label for the password input
378 SUBMIT_LABEL (default: Sign In)
380 the label for the submit button
381 COMMENT (default: Please enter your username and password in the
383 fields below.)
384 a message provided on the first login attempt
385 REMEMBERUSER_OPTION (default: 1)
387 provide a checkbox to offer to remember the users name in a
388 cookie so that their user name will be pre-filled the next time
389 they log in
390 REMEMBERUSER_LABEL (default: Remember User Name)
392 the label for the remember user name checkbox
393 REMEMBERUSER_COOKIENAME (default: CAPAUTHTOKEN)
395 the name of the cookie where the user name will be saved
396 REGISTER_URL (default: <none>)
398 the URL for the register new account link
399 REGISTER_LABEL (default: Register Now!)
401 the label for the register new account link
402 FORGOTPASSWORD_URL (default: <none>)
404 the URL for the forgot password link
405 FORGOTPASSWORD_LABEL (default: Forgot Password?)
407 the label for the forgot password link
408 INVALIDPASSWORD_MESSAGE (default: Invalid username or password<br
410 />(login attempt %d)
411 a message given when a login failed
412 INCLUDE_STYLESHEET (default: 1)
414 use this to disable the built in style-sheet for the login box
415 so you can provide your own custom styles
416 FORM_SUBMIT_METHOD (default: post)
418 use this to get the form to submit using 'get' instead of
419 'post'
420 FOCUS_FORM_ONLOAD (default: 1)
422 use this to automatically focus the login form when the page
423 loads so a user can start typing right away.
424 BASE_COLOUR (default: #445588)
426 This is the base colour that will be used in the included login
427 box. All other colours are automatically calculated based on
428 this colour (unless you hardcode the colour values). In order
429 to calculate other colours, you will need the Color::Calc
430 module. If you do not have the Color::Calc module, then you
431 will need to use fixed values for all of the colour options.
432 All colour values besides the BASE_COLOUR can be simple
433 percentage values (including the % sign). For example if you
434 set the LIGHTER_COLOUR option to 80%, then the calculated
435 colour will be 80% lighter than the BASE_COLOUR.
436 LIGHT_COLOUR (default: 50% or #a2aac4)
438 A colour that is lighter than the base colour.
439 LIGHTER_COLOUR (default: 75% or #d0d5e1)
441 A colour that is another step lighter than the light colour.
442 DARK_COLOUR (default: 30% or #303c5f)
444 A colour that is darker than the base colour.
445 DARKER_COLOUR (default: 60% or #1b2236)
447 A colour that is another step darker than the dark colour.
448 GREY_COLOUR (default: #565656)
450 A grey colour that is calculated by desaturating the base
451 colour.
452 protected_runmodes
454 This method takes a list of runmodes that are to be protected by
455 authentication. If a user tries to access one of these runmodes, then
456 they will be redirected to a login page unless they are properly logged
457 in. The runmode names can be a list of simple strings, regular
458 expressions, or special directives that start with a colon. This
459 method is cumulative, so if it is called multiple times, the new values
460 are added to existing entries. It returns a list of all entries that
461 have been saved so far. Calling this function, will not itself
462 generate cookies or session ids.
463 :all - All runmodes in this module will require authentication
465 # match all runmodes
467 __PACKAGE__->authen->protected_runmodes(':all');
468 # only protect runmodes one two and three
470 __PACKAGE__->authen->protected_runmodes(qw(one two three));
471 # protect only runmodes that start with auth_
473 __PACKAGE__->authen->protected_runmodes(qr/^auth_/);
474 # protect all runmodes that *do not* start with public_
476 __PACKAGE__->authen->protected_runmodes(qr/^(?!public_)/);
477 is_protected_runmode
479 This method accepts the name of a runmode, and will tell you if that
480 runmode is a protected runmode (i.e. does a user need to be
481 authenticated to access this runmode). Calling this function, will not
482 itself generate cookies or session ids.
483 redirect_after_login
485 This method is be called during the prerun stage to redirect the user
486 to the page that has been configured as the destination after a
487 successful login. The location is determined as follows:
488 POST_LOGIN_RUNMODE
490 If the POST_LOGIN_RUNMODE config parameter is set, that run mode
491 will be the chosen location.
492 POST_LOGIN_URL
494 If the above fails and the POST_LOGIN_URL config parameter is set,
495 then there will be a 302 redirection to that location.
496 destination
498 If the above fails and there is a destination query parameter,
499 which must a taint check against the DETAINT_URL_REGEXP config
500 parameter, then there will be a 302 redirection to that location.
501 original destination
503 If all the above fail then there the originally requested page will
504 be delivered.
505 redirect_to_login
507 This method is be called during the prerun stage if the current user is
508 not logged in, and they are trying to access a protected runmode. It
509 will redirect to the page that has been configured as the login page,
510 based on the value of LOGIN_RUNMODE or LOGIN_URL If nothing is
511 configured a simple login page will be automatically provided.
512 redirect_to_logout
514 This method is called during the prerun stage if the user has requested
515 to be logged out. It will redirect to the page that has been
516 configured as the logout page, based on the value of LOGOUT_RUNMODE or
517 LOGOUT_URL If nothing is configured, the page will redirect to the
518 website homepage.
519 setup_runmodes
521 This method is called during the prerun stage to register some custom
522 runmodes that the Authentication plugin requires in order to function.
523 Calling this function, will not itself generate cookies or session ids.
524 last_login
526 This will return return the time of the last login for this user
527 my $last_login = $self->authen->last_login;
529 This function will initiate a session or cookie if one has not been
531 created already.
532 last_access
534 This will return return the time of the last access for this user
535 my $last_access = $self->authen->last_access;
537 This function will initiate a session or cookie if one has not been
539 created already.
540 is_login_timeout
542 This will return true or false depending on whether the users login
543 status just timed out
544 $self->add_message('login session timed out') if $self->authen->is_login_timeout;
546 This function will initiate a session or cookie if one has not been
548 created already.
549 is_authenticated
551 This will return true or false depending on the login status of this
552 user
553 assert($self->authen->is_authenticated); # The user should be logged in if we got here
555 This function will initiate a session or cookie if one has not been
557 created already.
558 login_attempts
560 This method will return the number of failed login attempts have been
561 made by this user since the last successful login. This is not a
562 number that can be trusted, as it is dependent on the underlying store
563 to be able to return the correct value for this user. For example, if
564 the store uses a cookie based session, the user trying to login could
565 delete their cookies, and hence get a new session which will not have
566 any login attempts listed. The number will be cleared upon a
567 successful login. This function will initiate a session or cookie if
568 one has not been created already.
569 username
571 This will return the username of the currently logged in user, or undef
572 if no user is currently logged in.
573 my $username = $self->authen->username;
575 This function will initiate a session or cookie if one has not been
577 created already.
578 is_new_login
580 This will return true or false depending on if this is a fresh login
581 $self->log->info("New Login") if $self->authen->is_new_login;
583 This function will initiate a session or cookie if one has not been
585 created already.
586 credentials
588 This method will return the names of the form parameters that will be
589 looked for during a login. By default they are authen_username and
590 authen_password, but these values can be changed by supplying the
591 CREDENTIALS parameters in the configuration. Calling this function,
592 will not itself generate cookies or session ids.
593 logout
595 This will attempt to logout the user. If during a request the
596 Authentication module sees a parameter called 'authen_logout', it will
597 automatically call this method to log out the user.
598 $self->authen->logout();
600 This function will initiate a session or cookie if one has not been
602 created already.
603 drivers
605 This method will return a list of driver objects that are used for
606 verifying the login credentials. Calling this function, will not itself
607 generate cookies or session ids.
608 store
610 This method will return a store object that is used to store
611 information about the status of the authentication across multiple
612 requests. This function will initiate a session or cookie if one has
613 not been created already.
614 initialize
616 This does most of the heavy lifting for the Authentication plugin. It
617 will check to see if the user is currently attempting to login by
618 looking for the credential form fields in the query object. It will
619 load the required driver objects and authenticate the user. It is OK
620 to call this method multiple times as it checks to see if it has
621 already been executed and will just return without doing anything if
622 called multiple times. This allows us to call initialize as late as
623 possible in the request so that no unnecessary work is done.
624 The user will be logged out by calling the "logout()" method if the
626 login session has been idle for too long, if it has been too long since
627 the last login, or if the login has timed out. If you need to know if
628 a user was logged out because of a time out, you can call the
629 "is_login_timeout" method.
630 If all goes well, a true value will be returned, although it is usually
632 not necessary to check.
633 This function will initiate a session or cookie if one has not been
635 created already.
636 display
638 This method will return the
639 CGI::Application::Plugin::Authentication::Display object, creating and
640 caching it if necessary.
641 login_box
643 This method will return the HTML for a login box that can be embedded
644 into another page. This is the same login box that is used in the
645 default authen_login runmode that the plugin provides.
646 This function will initiate a session or cookie if one has not been
648 created already.
649 new
651 This method creates a new CGI::Application::Plugin::Authentication
652 object. It requires as it's only parameter a CGI::Application object.
653 This method should never be called directly, since the 'authen' method
654 that is imported into the CGI::Application module will take care of
655 creating the CGI::Application::Plugin::Authentication object when it is
656 required. Calling this function, will not itself generate cookies or
657 session ids.
658 instance
660 This method works the same way as 'new', except that it returns the
661 same Authentication object for the duration of the request. This
662 method should never be called directly, since the 'authen' method that
663 is imported into the CGI::Application module will take care of creating
664 the CGI::Application::Plugin::Authentication object when it is
665 required. Calling this function, will not itself generate cookies or
666 session ids.
667
669 prerun_callback
670 This method is a CGI::Application prerun callback that will be
671 automatically registered for you if you are using CGI::Application 4.0
672 or greater. If you are using an older version of CGI::Application you
673 will have to create your own cgiapp_prerun method and make sure you
674 call this method from there.
675 sub cgiapp_prerun {
677 my $self = shift;
678 $self->CGI::Application::Plugin::Authentication::prerun_callback();
680 }
681
683 authen_login_runmode
684 This runmode is provided if you do not want to create your own login
685 runmode. It will display a simple login form for the user, which can
686 be replaced by assigning RENDER_LOGIN a coderef that returns the HTML.
687 authen_dummy_redirect
689 This runmode is provided for convenience when an external redirect
690 needs to be done. It just returns an empty string.
691
693 In a CGI::Application module:
694 use base qw(CGI::Application);
696 use CGI::Application::Plugin::AutoRunmode;
697 use CGI::Application::Plugin::Session;
698 use CGI::Application::Plugin::Authentication;
699 __PACKAGE__->authen->config(
701 DRIVER => [ 'Generic', { user1 => '123' } ],
702 STORE => 'Session',
703 LOGOUT_RUNMODE => 'start',
704 );
705 __PACKAGE__->authen->protected_runmodes(qr/^auth_/, 'one');
706 sub start : RunMode {
708 my $self = shift;
709 }
711 sub one : RunMode {
713 my $self = shift;
714 # The user will only get here if they are logged in
716 }
717 sub auth_two : RunMode {
719 my $self = shift;
720 # This is also protected because of the
722 # regexp call to protected_runmodes above
723 }
724
726 The prerun callback has been modified so that it will check for the
727 presence of a prerun mode. This is for compatibility with
728 CGI::Application::Plugin::ActionDispatch. This change should be
729 considered experimental. It is necessary to load the ActionDispatch
730 module so that the two prerun callbacks will be called in the correct
731 order.
732
734 CSS The best practice nowadays is generally considered to be to not
735 have CSS embedded in HTML. Thus it should be best to set LOGIN_FORM
736 -> DISPLAY_CLASS to 'Basic'.
737 Post login destination
739 Of the various means of selecting a post login destination the most
740 secure would seem to be POST_LOGIN_URL. The "destination" parameter
741 could potentially be hijacked by hackers. The POST_LOGIN_RUNMODE
742 parameter requires a hidden parameter that could potentially be
743 hijacked.
744 Taint mode
746 Do run your code under taint mode. It should help protect your
747 application against a number of attacks.
748 URL and username checking
750 Please set the "DETAINT_URL_REGEXP" and "DETAINT_USERNAME_REGEXP"
751 parameters as tightly as possible. In particular you should prevent
752 the destination parameter being used to redirect authenticated
753 users to external sites; unless of course that is what you want in
754 which case that site should be the only possible external site.
755 The login form
757 The HTML currently generated does not seem to be standards
758 compliant as per RT bug 58023. Also the default login form includes
759 hidden forms which could conceivably be hijacked. Set LOGIN_FORM
760 -> DISPLAY_CLASS to 'Basic' to fix this.
761
763 There are lots of things that can still be done to improve this plugin.
764 If anyone else is interested in helping out feel free to dig right in.
765 Many of these things don't need my input, but if you want to avoid
766 duplicated efforts, send me a note, and I'll let you know of anyone
767 else is working in the same area.
768 review the code for security bugs and report
770 complete the separation of presentation and logic
771 write a tutorial
772 build more Drivers (Class::DBI, LDAP, Radius, etc...)
773 Add support for method attributes to identify runmodes that require
774 authentication
775 finish the test suite
776 provide more example code
777 clean up the documentation
778 build a DB driver that builds it's own table structure. This can be
779 used by people that don't have their own user database to work with,
780 and could include a simple user management application.
781
783 This is alpha software and as such, the features and interface are
784 subject to change. So please check the Changes file when upgrading.
785 Some of the test scripts appear to be incompatible with versions of
787 Devel::Cover later than 0.65.
