6 slapd-perl - Perl backend to slapd
7
9 /etc/openldap/slapd.conf
10
12 The Perl backend to slapd(8) works by embedding a perl(1) interpreter
13 into slapd(8). Any perl database section of the configuration file
14 slapd.conf(5) must then specify what Perl module to use. Slapd then
15 creates a new Perl object that handles all the requests for that par‐
16 ticular instance of the backend.
17
18 You will need to create a method for each one of the following actions:
19
20 * new # creates a new object,
21 * search # performs the ldap search,
22 * compare # does a compare,
23 * modify # modifies an entry,
24 * add # adds an entry to backend,
25 * modrdn # modifies an entry's rdn,
26 * delete # deletes an ldap entry,
27 * config # process unknown config file lines,
28 * init # called after backend is initialized.
29
30 Unless otherwise specified, the methods return the result code which
31 will be returned to the client. Unimplemented actions can just return
32 unwillingToPerform (53).
33
34 new This method is called when the configuration file encounters a
35 perlmod line. The module in that line is then effectively
36 `use'd into the perl interpreter, then the new method is called
37 to create a new object. Note that multiple instances of that
38 object may be instantiated, as with any perl object. The new
39 method receives the class name as argument.
40
41 search This method is called when a search request comes from a client.
42 It arguments are as follows:
43 * object reference
44 * base DN
45 * scope
46 * alias dereferencing policy
47 * size limit
48 * time limit
49 * filter string
50 * attributes only flag (1 for yes)
51 * list of attributes to return (may be empty)
52
53 Return value: (resultcode, ldif-entry, ldif-entry, ...)
54
55 compare
56 This method is called when a compare request comes from a
57 client. Its arguments are as follows.
58 * object reference
59 * dn
60 * attribute assertion string
61
62 modify This method is called when a modify request comes from a client.
63 Its arguments are as follows.
64 * object reference
65 * dn
66 * a list formatted as follows
67 ({ "ADD" | "DELETE" | "REPLACE" },
68 attributetype, value...)...
69
70 add This method is called when a add request comes from a client.
71 Its arguments are as follows.
72 * object reference
73 * entry in string format
74
75 modrdn This method is called when a modrdn request comes from a client.
76 Its arguments are as follows.
77 * object reference
78 * dn
79 * new rdn
80 * delete old dn flag (1 means yes)
81
82 delete This method is called when a delete request comes from a client.
83 Its arguments are as follows.
84 * object reference
85 * dn
86
87 config This method is called with unknown slapd.conf(5) configuration
88 file lines. Its arguments are as follows.
89 * object reference
90 * array of arguments on line
91
92 Return value: nonzero if this is not a valid option.
93
94 init This method is called after backend is initialized. Its argu‐
95 ment is as follows.
96 * object reference
97
98 Return value: nonzero if initialization failed.
99
101 These slapd.conf options apply to the PERL backend database. That is,
102 they must follow a "database perl" line and come before any subsequent
103 "backend" or "database" lines. Other database options are described in
104 the slapd.conf(5) manual page.
105
106 perlModulePath /path/to/libs
107 Add the path to the @INC variable.
108
109 perlModule ModName
110 `Use' the module name ModName from ModName.pm
111
112 filterSearchResults
113 Search results are candidates that need to be filtered (with the
114 filter in the search request), rather than search results to be
115 returned directly to the client.
116
118 There is an example Perl module `SampleLDAP' in the slapd/back-perl/
119 directory in the OpenLDAP source tree.
120
122 The passwd backend does not honor any of the access control semantics
123 described in slapd.access(5); all access control is delegated to the
124 underlying PERL scripting. Only read (=r) access to the entry pseudo-
125 attribute and to the other attribute values of the entries returned by
126 the search operation is honored, which is performed by the frontend.
127
129 The interface of this backend to the perl module MAY change. Any sug‐
130 gestions would greatly be appreciated.
