6 slapo-ppolicy - Password Policy overlay to slapd
7
9 /etc/openldap/slapd.conf
10
12 The ppolicy overlay is an implementation of the most recent IETF Pass‐
13 word Policy proposal for LDAP. When instantiated, it intercepts, de‐
14 codes and applies specific password policy controls to overall use of a
15 backend database, changes to user password fields, etc.
16 The overlay provides a variety of password control mechanisms. They
18 include password aging -- both minimum and maximum ages, password reuse
19 and duplication control, account time-outs, mandatory password resets,
20 acceptable password content, and even grace logins. Different groups
21 of users may be associated with different password policies, and there
22 is no limit to the number of password policies that may be created.
23 Note that some of the policies do not take effect when the operation is
25 performed with the rootdn identity; all the operations, when performed
26 with any other identity, may be subjected to constraints, like access
27 control. This overlay requires a rootdn to be configured on the data‐
28 base.
29 During password update, an identity with manage access to the userPass‐
31 word attribute is considered a password administrator where relevant to
32 the IETF Password Policy proposal.
33 Note that the IETF Password Policy proposal for LDAP makes sense when
35 considering a single-valued password attribute, while the userPassword
36 attribute allows multiple values. This implementation enforces a sin‐
37 gle value for the userPassword attribute, despite its specification.
38 In addition to supporting the IETF Password Policy, this module sup‐
40 ports the SunDS Account Usability control (1.3.6.1.4.1.42.2.27.9.5.8)
41 on search requests and can send the Netscape Password validity controls
42 when configured to do so.
43
46 These slapd.conf configuration options apply to the ppolicy overlay.
47 They should appear after the overlay directive.
48 ppolicy_default <policyDN>
50 Specify the DN of the pwdPolicy object to use when no specific
51 policy is set on a given user's entry. If there is no specific
52 policy for an entry and no default is given, then no policies
53 will be enforced.
54 ppolicy_forward_updates
56 Specify that policy state changes that result from Bind opera‐
57 tions (such as recording failures, lockout, etc.) on a consumer
58 should be forwarded to a provider instead of being written di‐
59 rectly into the consumer's local database. This setting is only
60 useful on a replication consumer, and also requires the up‐
61 dateref setting and chain overlay to be appropriately config‐
62 ured.
63 ppolicy_hash_cleartext
65 Specify that cleartext passwords present in Add and Modify re‐
66 quests should be hashed before being stored in the database.
67 This violates the X.500/LDAP information model, but may be
68 needed to compensate for LDAP clients that don't use the Pass‐
69 word Modify extended operation to manage passwords. It is rec‐
70 ommended that when this option is used that compare, search, and
71 read access be denied to all directory users.
72 ppolicy_use_lockout
74 A client will always receive an LDAP InvalidCredentials response
75 when Binding to a locked account. By default, when a Password
76 Policy control was provided on the Bind request, a Password Pol‐
77 icy response will be included with no special error code set.
78 This option changes the Password Policy response to include the
79 AccountLocked error code. Note that sending the AccountLocked
80 error code provides useful information to an attacker; sites
81 that are sensitive to security issues should not enable this op‐
82 tion.
83 ppolicy_send_netscape_controls
85 If set, ppolicy will send the password policy expired
86 (2.16.840.1.113730.3.4.4) and password policy expiring
87 (2.16.840.1.113730.3.4.5) controls when appropriate. The con‐
88 trols are not sent for bind requests where the Password policy
89 control has already been requested. Default is not to send the
90 controls.
91 ppolicy_check_module <path>
93 Specify the path of a loadable module containing a check_pass‐
94 word() function for additional password quality checks. The use
95 of this module is described further below in the description of
96 the pwdPolicyChecker objectclass.
97 Note: The user-defined loadable module must be in slapd's stan‐
99 dard executable search PATH, or an absolute path must be pro‐
100 vided.
101 Note: Use of a ppolicy_check_module is a non-standard extension
103 to the LDAP password policy proposal.
104
108 The ppolicy overlay depends on the pwdPolicy object class. The defini‐
109 tion of that class is as follows:
110 ( 1.3.6.1.4.1.42.2.27.8.2.1

122 pwdMustChange $ pwdAllowUserChange $
123 pwdSafeModify $ pwdMaxRecordedFailure $
124 pwdMinDelay $ pwdMaxDelay $ pwdMaxIdle ) )
125 The pwdPolicy class is not structural, and so entries using it require
127 another, structural, object class. The namedPolicy object class is a
128 good choice. namedPolicy requires a cn attribute, suitable as the pol‐
129 icy entry's rDN.
130 This implementation also provides an additional pwdPolicyChecker ob‐
132 jectclass, used for password quality checking (see below).

140 Every account that should be subject to password policy control should
142 have a pwdPolicySubentry attribute containing the DN of a valid pwdPol‐
143 icy entry, or they can simply use the configured default. In this way
144 different users may be managed according to different policies.
145
148 Each one of the sections below details the meaning and use of a partic‐
149 ular attribute of this pwdPolicy object class.
150 pwdAttribute
152 This attribute contains the name of the attribute to which the password
154 policy is applied. For example, the password policy may be applied to
155 the userPassword attribute.
156 Note: in this implementation, the only value accepted for pwdAttribute
158 is userPassword .

193 that will be stored in the pwdHistory attribute. If the pwdInHistory
194 attribute is not present, or if its value is zero (0), used passwords
195 will not be stored in pwdHistory and thus any previously-used password
196 may be reused. No history checking occurs if the password is being
197 modified by the rootdn, although the password is saved in the history.

210 its value is one (1), the server will check the syntax, and if the
211 server is unable to check the syntax, whether due to a client-side
212 hashed password or some other reason, it will be accepted. If its value
213 is two (2), the server will check the syntax, and if the server is un‐

229 some other reason, the server will, depending on the value of pwdCheck‐
230 Quality, either accept the password without checking it (if pwdCheck‐
231 Quality is zero (0) or one (1)) or refuse it (if pwdCheckQuality is two
232 (2)). If the number of characters should be enforced with regards to a

382 users must change their passwords when they first bind to the directory

399 passwords. If its value is "FALSE", users will not be allowed to
400 change their own passwords.
401 Note: this implies that when pwdAllowUserChange is set to "TRUE", users
403 will still be able to change the password of another user, subjected to
404 access control. This restriction only applies to modifications of
405 ones's own password. It should also be noted that pwdAllowUserChange
406 was defined in the specification to provide rough access control to the
407 password attribute in implementations that do not allow fine-grain ac‐
408 cess control. Since OpenLDAP provides fine-grain access control, the
409 use of this attribute is discouraged; ACLs should be used instead (see

483 pwdUseCheckModule/pwdCheckModuleArg
485 The pwdUseCheckModule attribute enables use of a loadable module previ‐
487 ously configured with ppolicy_check_module for the current policy. The
488 module must instantiate the check_password() function. This function
489 will be called to further check a new password if pwdCheckQuality is
490 set to one (1) or two (2), after all of the built-in password compli‐
491 ance checks have been passed. This function will be called according
492 to this function prototype:
493 int check_password (char *pPasswd, struct berval *pErrmsg, Entry
494 *pEntry, struct berval *pArg);
495 The pPasswd parameter contains the clear-text user password, the pEr‐
496 rmsg parameter points to a struct berval containing space to return hu‐
497 man-readable details about any error it encounters. The bv_len field
498 must contain the size of the space provided by the bv_val field.
499 The pEntry parameter is optional, if non-NULL, carries a pointer to the
501 entry whose password is being checked.
502 The optional pArg parameter points to a struct berval containing the
504 value of pwdCheckModuleArg in the effective password policy, if set,
505 otherwise NULL.
506 If pErrmsg is NULL, then funcName must NOT attempt to use it. A return
508 value of LDAP_SUCCESS from the called function indicates that the pass‐
509 word is ok, any other value indicates that the password is unaccept‐
510 able. If the password is unacceptable, the server will return an error
511 to the client, and pErrmsg may be used to return a human-readable tex‐
512 tual explanation of the error. If the space passed in by the caller is
513 too small, the function may replace it with a dynamically allocated
514 buffer, which will be free()'d by slapd.
515 The pwdCheckModule attribute is now obsolete and is ignored.

541 The operational attributes used by the ppolicy module are stored in the
542 user's entry. Most of these attributes are not intended to be changed
543 directly by users; they are there to track user activity. They have
544 been detailed here so that administrators and users can both understand
545 the workings of the ppolicy module.
546 Note that the current IETF Password Policy proposal does not define how
549 these operational attributes are expected to behave in a replication
550 environment. In general, authentication attempts on a replica server
551 only affect the copy of the operational attributes on that replica and
552 will not affect any attributes for a user's entry on the provider. Op‐
553 erational attribute changes resulting from authentication attempts on a
554 provider will usually replicate to the replicas (and also overwrite any
555 changes that originated on the replica). These behaviors are not guar‐
556 anteed and are subject to change when a formal specification emerges.
557 userPassword
559 The userPassword attribute is not strictly part of the ppolicy module.
561 It is, however, the attribute that is tracked and controlled by the

563 tion.
564 pwdPolicySubentry
566 This attribute refers directly to the pwdPolicy subentry that is to be
568 used for this particular directory user. If pwdPolicySubentry exists,
569 it must contain the DN of a valid pwdPolicy object. If it does not ex‐
570 ist, the ppolicy module will enforce the default password policy rules
571 on the user associated with this authenticating DN. If there is no de‐
572 fault, or the referenced subentry does not exist, then no policy rules
573 will be enforced.

583 pwdChangedTime
585 This attribute denotes the last time that the entry's password was
587 changed. This value is used by the password expiration policy to de‐
588 termine whether the password is too old to be allowed to be used for
589 user authentication. If pwdChangedTime does not exist, the user's
590 password will not expire.

603 This attribute contains the time that the user's account was locked.
605 If the account has been locked, the password may no longer be used to
606 authenticate the user to the directory. If pwdAccountLockedTime is set
607 to 000001010000Z, the user's account has been permanently locked and
608 may only be unlocked by an administrator. Note that account locking
609 only takes effect when the pwdLockout password policy attribute is set
610 to "TRUE".

625 (i.e. account). If too many timestamps accumulate here (refer to the
626 pwdMaxFailure password policy attribute for details), and the pwdLock‐
627 out password policy attribute is set to "TRUE", the account may be
628 locked. (Please also refer to the pwdLockout password policy attri‐
629 bute.) Excess timestamps beyond those allowed by pwdMaxFailure or pwd‐
630 MaxRecordedFailure may also be purged. If a successful authentication
631 is made to this DN (i.e. to this user account), then pwdFailureTime
632 will be cleansed of entries.

643 pwdHistory
645 This attribute contains the history of previously used passwords for
647 this DN (i.e. for this user account). The values of this attribute are
648 stored in string format as follows:
649 pwdHistory=
652 time "#" syntaxOID "#" length "#" data
653 time=
655 GeneralizedTime as specified in section 3.3.13 of [RFC4517]
656 syntaxOID = numericoid
659 This is the string representation of the dotted-decimal OID
660 that defines the syntax used to store the password. numericoid
661 is described in section 1.4 of [RFC4512].
662 length = NumericString
664 The number of octets in the data. NumericString is described
665 in section 3.3.23 of [RFC4517].
666 data =
668 Octets representing the password in the format specified by
669 syntaxOID.
670 This format allows the server to store and transmit a history of pass‐
673 words that have been used. In order for equality matching on the val‐
674 ues in this attribute to function properly, the time field is in GMT
675 format.

689 known as "grace logins". If too many grace logins have been used
690 (please refer to the pwdGraceAuthnLimit password policy attribute),
691 then the DN will no longer be allowed to be used to authenticate the
692 user to the directory until the administrator changes the DN's user‐

705 This attribute indicates whether the user's password has been reset by
707 the administrator and thus must be changed upon first use of this DN
708 for authentication to the directory. If pwdReset is set to "TRUE",
709 then the password was reset and the user must change it upon first au‐
710 thentication. If the attribute does not exist, or is set to "FALSE",
711 the user need not change their password due to administrative reset.

803 The LDAP Password Policy specification is not yet an approved standard,
804 and it is still evolving. This code will continue to be in flux until
805 the specification is finalized.

809 This module was written in 2004 by Howard Chu of Symas Corporation with
810 significant input from Neil Dunbar and Kartik Subbarao of Hewlett-
811 Packard.
812 This manual page borrows heavily and shamelessly from the specification
814 upon which the password policy module it describes is based. This
815 source is the IETF LDAP password policy proposal by P. Behera, L.
816 Poitou and J. Sermersheim. The proposal is fully documented in the
817 IETF document named draft-behera-ldap-password-policy-10.txt, written
818 in August of 2009.
