SLAPO_PPOLICY(5) File Formats Manual SLAPO_PPOLICY(5) NAME slapo-ppolicy - Password Policy overlay to slapd SYNOPSIS /usr/local/etc/openldap/slapd.conf DESCRIPTION The ppolicy overlay is an implementation of the most recent IETF Pass- word Policy proposal for LDAP. When instantiated, it intercepts, de- codes and applies specific password policy controls to overall use of a backend database, changes to user password fields, etc. The overlay provides a variety of password control mechanisms. They include password aging -- both minimum and maximum ages, password reuse and duplication control, account time-outs, mandatory password resets, acceptable password content, and even grace logins. Different groups of users may be associated with different password policies, and there is no limit to the number of password policies that may be created. Note that some of the policies do not take effect when the operation is performed with the rootdn identity; all the operations, when performed with any other identity, may be subjected to constraints, like access control. This overlay requires a rootdn to be configured on the data- base. During password update, an identity with manage access to the userPass- word attribute is considered a password administrator where relevant to the IETF Password Policy proposal. Note that the IETF Password Policy proposal for LDAP makes sense when considering a single-valued password attribute, while the userPassword attribute allows multiple values. This implementation enforces a sin- gle value for the userPassword attribute, despite its specification. In addition to supporting the IETF Password Policy, this module sup- ports the SunDS Account Usability control (1.3.6.1.4.1.42.2.27.9.5.8) on search requests and can send the Netscape Password validity controls when configured to do so. CONFIGURATION These slapd.conf configuration options apply to the ppolicy overlay. They should appear after the overlay directive. ppolicy_default <policyDN> Specify the DN of the pwdPolicy object to use when no specific policy is set on a given user's entry. If there is no specific policy for an entry and no default is given, then no policies will be enforced. ppolicy_forward_updates Specify that policy state changes that result from Bind opera- tions (such as recording failures, lockout, etc.) on a consumer should be forwarded to a provider instead of being written di- rectly into the consumer's local database. This setting is only useful on a replication consumer, and also requires the up- dateref setting and chain overlay to be appropriately config- ured. ppolicy_hash_cleartext Specify that cleartext passwords present in Add and Modify re- quests should be hashed before being stored in the database. This violates the X.500/LDAP information model, but may be needed to compensate for LDAP clients that don't use the Pass- word Modify extended operation to manage passwords. It is rec- ommended that when this option is used that compare, search, and read access be denied to all directory users. ppolicy_use_lockout A client will always receive an LDAP InvalidCredentials response when Binding to a locked account. By default, when a Password Policy control was provided on the Bind request, a Password Pol- icy response will be included with no special error code set. This option changes the Password Policy response to include the AccountLocked error code. Note that sending the AccountLocked error code provides useful information to an attacker; sites that are sensitive to security issues should not enable this op- tion. ppolicy_send_netscape_controls If set, ppolicy will send the password policy expired (2.16.840.1.113730.3.4.4) and password policy expiring (2.16.840.1.113730.3.4.5) controls when appropriate. The con- trols are not sent for bind requests where the Password policy control has already been requested. Default is not to send the controls. ppolicy_check_module <path> Specify the path of a loadable module containing a check_pass- word() function for additional password quality checks. The use of this module is described further below in the description of the pwdPolicyChecker objectclass. Note: The user-defined loadable module must be in slapd's stan- dard executable search PATH, or an absolute path must be pro- vided. Note: Use of a ppolicy_check_module is a non-standard extension to the LDAP password policy proposal. OBJECT CLASS The ppolicy overlay depends on the pwdPolicy object class. The defini- tion of that class is as follows: ( 1.3.6.1.4.1.42.2.27.8.2.1 NAME 'pwdPolicy' AUXILIARY SUP top MUST ( pwdAttribute ) MAY ( pwdMinAge $ pwdMaxAge $ pwdInHistory $ pwdCheckQuality $ pwdMinLength $ pwdMaxLength $ pwdExpireWarning $ pwdGraceAuthnLimit $ pwdGraceExpiry $ pwdLockout $ pwdLockoutDuration $ pwdMaxFailure $ pwdFailureCountInterval $ pwdMustChange $ pwdAllowUserChange $ pwdSafeModify $ pwdMaxRecordedFailure $ pwdMinDelay $ pwdMaxDelay $ pwdMaxIdle ) ) The pwdPolicy class is not structural, and so entries using it require another, structural, object class. The namedPolicy object class is a good choice. namedPolicy requires a cn attribute, suitable as the pol- icy entry's rDN. This implementation also provides an additional pwdPolicyChecker ob- jectclass, used for password quality checking (see below). ( 1.3.6.1.4.1.4754.2.99.1 NAME 'pwdPolicyChecker' AUXILIARY SUP top MAY ( pwdCheckModule $ pwdCheckModuleArg $ pwdUseCheckModule ) ) Every account that should be subject to password policy control should have a pwdPolicySubentry attribute containing the DN of a valid pwdPol- icy entry, or they can simply use the configured default. In this way different users may be managed according to different policies. OBJECT CLASS ATTRIBUTES Each one of the sections below details the meaning and use of a partic- ular attribute of this pwdPolicy object class. pwdAttribute This attribute contains the name of the attribute to which the password policy is applied. For example, the password policy may be applied to the userPassword attribute. Note: in this implementation, the only value accepted for pwdAttribute is userPassword . ( 1.3.6.1.4.1.42.2.27.8.1.1 NAME 'pwdAttribute' EQUALITY objectIdentifierMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 ) pwdMinAge This attribute contains the number of seconds that must elapse between modifications allowed to the password. If this attribute is not present, zero seconds is assumed (i.e. the password may be modified whenever and however often is desired). ( 1.3.6.1.4.1.42.2.27.8.1.2 NAME 'pwdMinAge' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMaxAge This attribute contains the number of seconds after which a modified password will expire. If this attribute is not present, or if its value is zero (0), then passwords will not expire. ( 1.3.6.1.4.1.42.2.27.8.1.3 NAME 'pwdMaxAge' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdInHistory This attribute is used to specify the maximum number of used passwords that will be stored in the pwdHistory attribute. If the pwdInHistory attribute is not present, or if its value is zero (0), used passwords will not be stored in pwdHistory and thus any previously-used password may be reused. No history checking occurs if the password is being modified by the rootdn, although the password is saved in the history. ( 1.3.6.1.4.1.42.2.27.8.1.4 NAME 'pwdInHistory' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdCheckQuality This attribute indicates if and how password syntax will be checked while a password is being modified or added. If this attribute is not present, or its value is zero (0), no syntax checking will be done. If its value is one (1), the server will check the syntax, and if the server is unable to check the syntax, whether due to a client-side hashed password or some other reason, it will be accepted. If its value is two (2), the server will check the syntax, and if the server is un- able to check the syntax it will return an error refusing the password. ( 1.3.6.1.4.1.42.2.27.8.1.5 NAME 'pwdCheckQuality' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMinLength When syntax checking is enabled (see also the pwdCheckQuality at- tribute), this attribute contains the minimum length in bytes that will be accepted in a password. If this attribute is not present, minimum password length is not enforced. If the server is unable to check the length of the password, whether due to a client-side hashed password or some other reason, the server will, depending on the value of pwdCheck- Quality, either accept the password without checking it (if pwdCheck- Quality is zero (0) or one (1)) or refuse it (if pwdCheckQuality is two (2)). If the number of characters should be enforced with regards to a particular encoding, the use of an appropriate ppolicy_check_module is required. ( 1.3.6.1.4.1.42.2.27.8.1.6 NAME 'pwdMinLength' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMaxLength When syntax checking is enabled (see also the pwdCheckQuality at- tribute), this attribute contains the maximum length in bytes that will be accepted in a password. If this attribute is not present, maximum password length is not enforced. If the server is unable to check the length of the password, whether due to a client-side hashed password or some other reason, the server will, depending on the value of pwdCheck- Quality, either accept the password without checking it (if pwdCheck- Quality is zero (0) or one (1)) or refuse it (if pwdCheckQuality is two (2)). If the number of characters should be enforced with regards to a particular encoding, the use of an appropriate ppolicy_check_module is required.

If this attribute is not present, or if the value is zero (0), no warnings will be sent. ( 1.3.6.1.4.1.42.2.27.8.1.7 NAME 'pwdExpireWarning' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdGraceAuthnLimit This attribute contains the number of times that an expired password may be used to authenticate a user to the directory. If this attribute is not present or if its value is zero (0), users with expired pass- words will not be allowed to authenticate to the directory. ( 1.3.6.1.4.1.42.2.27.8.1.8 NAME 'pwdGraceAuthnLimit' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdGraceExpiry This attribute specifies the number of seconds the grace authentica- tions are valid. If this attribute is not present or if the value is zero (0), there is no time limit on the grace authentications. ( 1.3.6.1.4.1.42.2.27.8.1.30 NAME 'pwdGraceExpiry' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdLockout This attribute specifies the action that should be taken by the direc- tory when a user has made a number of failed attempts to authenticate to the directory. If pwdLockout is set (its value is "TRUE"), the user will not be allowed to attempt to authenticate to the directory after there have been a specified number of consecutive failed bind attempts. The maximum number of consecutive failed bind attempts allowed is spec- ified by the pwdMaxFailure attribute. If pwdLockout is not present, or if its value is "FALSE", the password may be used to authenticate no matter how many consecutive failed bind attempts have been made. ( 1.3.6.1.4.1.42.2.27.8.1.9 NAME 'pwdLockout' EQUALITY booleanMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 SINGLE-VALUE ) pwdLockoutDuration This attribute contains the number of seconds during which the password cannot be used to authenticate the user to the directory due to too many consecutive failed bind attempts. (See also pwdLockout and pwd- MaxFailure.) If pwdLockoutDuration is not present, or if its value is zero (0), the password cannot be used to authenticate the user to the directory again until it is reset by an administrator. ( 1.3.6.1.4.1.42.2.27.8.1.10 NAME 'pwdLockoutDuration' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMaxFailure This attribute contains the number of consecutive failed bind attempts after which the password may not be used to authenticate a user to the directory. If pwdMaxFailure is not present, or its value is zero (0), then a user will be allowed to continue to attempt to authenticate to the directory, no matter how many consecutive failed bind attempts have occurred with that user's DN. (See also pwdLockout and pwdLockoutDura- tion.) ( 1.3.6.1.4.1.42.2.27.8.1.11 NAME 'pwdMaxFailure' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMaxRecordedFailure This attribute contains the maximum number of failed bind attempts to store in a user's entry. If pwdMaxRecordedFailure is not present, or its value is zero (0), then it defaults to the value of pwdMaxFailure. If that value is also 0, the default is 5. ( 1.3.6.1.4.1.42.2.27.8.1.32 NAME 'pwdMaxRecordedFailure' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdFailureCountInterval This attribute contains the number of seconds after which old consecu- tive failed bind attempts are purged from the failure counter, even though no successful authentication has occurred. If pwdFailure- CountInterval is not present, or its value is zero (0), the failure counter will only be reset by a successful authentication. ( 1.3.6.1.4.1.42.2.27.8.1.12 NAME 'pwdFailureCountInterval' EQUALITY integerMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMustChange This attribute specifies whether users must change their passwords when they first bind to the directory after a password is set or reset by the administrator, or not. If pwdMustChange has a value of "TRUE", users must change their passwords when they first bind to the directory after a password is set or reset by the administrator. If pwd- MustChange is not present, or its value is "FALSE", users are not re- quired to change their password upon binding after the administrator sets or resets the password. ( 1.3.6.1.4.1.42.2.27.8.1.13 NAME 'pwdMustChange' EQUALITY booleanMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 SINGLE-VALUE ) pwdAllowUserChange This attribute specifies whether users are allowed to change their own passwords or not. If pwdAllowUserChange is set to "TRUE", or if the attribute is not present, users will be allowed to change their own passwords. If its value is "FALSE", users will not be allowed to change their own passwords. Note: this implies that when pwdAllowUserChange is set to "TRUE", users will still be able to change the password of another user, subjected to access control. This restriction only applies to modifications of ones's own password. It should also be noted that pwdAllowUserChange was defined in the specification to provide rough access control to the password attribute in implementations that do not allow fine-grain ac- cess control. Since OpenLDAP provides fine-grain access control, the use of this attribute is discouraged; ACLs should be used instead (see slapd.access(5) for details). ( 1.3.6.1.4.1.42.2.27.8.1.14 NAME 'pwdAllowUserChange' EQUALITY booleanMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 SINGLE-VALUE ) pwdSafeModify This attribute denotes whether the user's existing password must be sent along with their new password when changing a password. If pwd- SafeModify is set to "TRUE", the existing password must be sent along with the new password. If the attribute is not present, or its value is "FALSE", the existing password need not be sent along with the new password. ( 1.3.6.1.4.1.42.2.27.8.1.15 NAME 'pwdSafeModify' EQUALITY booleanMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 SINGLE-VALUE ) pwdMinDelay This attribute specifies the number of seconds to delay responding to the first failed authentication attempt. If this attribute is not set or is zero (0), no delays will be used. pwdMaxDelay must also be spec- ified if pwdMinDelay is set. Note that this implementation uses a variable lockout instead of delay- ing the bind response. ( 1.3.6.1.4.1.42.2.27.8.1.24 NAME 'pwdMinDelay' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMaxDelay This attribute specifies the maximum number of seconds to delay when responding to a failed authentication attempt. The time specified in pwdMinDelay is used as the starting time and is then doubled on each failure until the delay time is greater than or equal to pwdMaxDelay (or a successful authentication occurs, which resets the failure counter). pwdMinDelay must also be specified if pwdMaxDelay is set. Note that this implementation uses a variable lockout instead of delay- ing the bind response. ( 1.3.6.1.4.1.42.2.27.8.1.25 NAME 'pwdMaxDelay' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdMaxIdle This attribute specifies the number of seconds an account may remain unused before it becomes locked. If this attribute is not set or is zero (0), no check is performed. For this to be enforced, lastbind functionality needs to be enabled on the database, that is olcLastBind is set to TRUE. ( 1.3.6.1.4.1.42.2.27.8.1.26 NAME 'pwdMaxIdle' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE ) pwdUseCheckModule/pwdCheckModuleArg The pwdUseCheckModule attribute enables use of a loadable module previ- ously configured with ppolicy_check_module for the current policy. The module must instantiate the check_password() function. This function will be called to further check a new password if pwdCheckQuality is set to one (1) or two (2), after all of the built-in password compli- ance checks have been passed. This function will be called according to this function prototype: int check_password (char *pPasswd, struct berval *pErrmsg, Entry *pEntry, struct berval *pArg); The pPasswd parameter contains the clear-text user password, the pEr- rmsg parameter points to a struct berval containing space to return hu- man-readable details about any error it encounters. The bv_len field must contain the size of the space provided by the bv_val field. The pEntry parameter is optional, if non-NULL, carries a pointer to the entry whose password is being checked. The optional pArg parameter points to a struct berval containing the value of pwdCheckModuleArg in the effective password policy, if set, otherwise NULL. If pErrmsg is NULL, then funcName must NOT attempt to use it. A return value of LDAP_SUCCESS from the called function indicates that the pass- word is ok, any other value indicates that the password is unaccept- able. If the password is unacceptable, the server will return an error to the client, and pErrmsg may be used to return a human-readable tex- tual explanation of the error. If the space passed in by the caller is too small, the function may replace it with a dynamically allocated buffer, which will be free()'d by slapd. The pwdCheckModule attribute is now obsolete and is ignored.

Most of these attributes are not intended to be changed directly by users; they are there to track user activity. They have been detailed here so that administrators and users can both understand the workings of the ppolicy module. Note that the current IETF Password Policy proposal does not define how these operational attributes are expected to behave in a replication environment. In general, authentication attempts on a replica server only affect the copy of the operational attributes on that replica and will not affect any attributes for a user's entry on the provider. Op- erational attribute changes resulting from authentication attempts on a provider will usually replicate to the replicas (and also overwrite any changes that originated on the replica). These behaviors are not guar- anteed and are subject to change when a formal specification emerges. userPassword The userPassword attribute is not strictly part of the ppolicy module. It is, however, the attribute that is tracked and controlled by the module. Please refer to the standard OpenLDAP schema for its defini- tion. pwdPolicySubentry This attribute refers directly to the pwdPolicy subentry that is to be used for this particular directory user. If pwdPolicySubentry exists, it must contain the DN of a valid pwdPolicy object. If it does not ex- ist, the ppolicy module will enforce the default password policy rules on the user associated with this authenticating DN. If there is no de- fault, or the referenced subentry does not exist, then no policy rules will be enforced.

This value is used by the password expiration policy to de- termine whether the password is too old to be allowed to be used for user authentication. If pwdChangedTime does not exist, the user's password will not expire.

If the account has been locked, the password may no longer be used to authenticate the user to the directory. If pwdAccountLockedTime is set to 000001010000Z, the user's account has been permanently locked and may only be unlocked by an administrator. Note that account locking only takes effect when the pwdLockout password policy attribute is set to "TRUE".

If too many timestamps accumulate here (refer to the pwdMaxFailure password policy attribute for details), and the pwdLock- out password policy attribute is set to "TRUE", the account may be locked. (Please also refer to the pwdLockout password policy at- tribute.) Excess timestamps beyond those allowed by pwdMaxFailure or pwdMaxRecordedFailure may also be purged. If a successful authentica- tion is made to this DN (i.e. to this user account), then pwdFailure- Time will be cleansed of entries.

The values of this attribute are stored in string format as follows: pwdHistory= time "#" syntaxOID "#" length "#" data time= GeneralizedTime as specified in section 3.3.13 of [RFC4517] syntaxOID = numericoid This is the string representation of the dotted-decimal OID that defines the syntax used to store the password. numericoid is described in section 1.4 of [RFC4512]. length = NumericString The number of octets in the data. NumericString is described in section 3.3.23 of [RFC4517]. data = Octets representing the password in the format specified by syntaxOID. This format allows the server to store and transmit a history of pass- words that have been used.
