NAME¶
slapo-ppolicy - Password Policy overlay to slapdSYNOPSIS¶
/etc/ldap/slapd.confDESCRIPTION¶
The ppolicy overlay is an implementation of the most recent IETF Password Policy proposal for LDAP. When instantiated, it intercepts, decodes 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. 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 single value for the userPassword attribute, despite its specification.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 operations (such as recording failures, lockout, etc.) on a consumer should be forwarded to a master instead of being written directly into the consumer's local database. This setting is only useful on a replication consumer, and also requires the updateref setting and chain overlay to be appropriately configured.
- ppolicy_hash_cleartext
- Specify that cleartext passwords present in Add and Modify requests 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 Password Modify extended operation to manage passwords. It is recommended 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 Policy 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 option.
OBJECT CLASS¶
The ppolicy overlay depends on the pwdPolicy object class. The definition 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 (

pwdMaxFailure $ pwdFailureCountInterval $
pwdMustChange $ pwdAllowUserChange $
pwdSafeModify 4 pwdMaxRecordedFailure ) )
This implementation also provides an additional pwdPolicyChecker
objectclass, used for password quality checking (see below).

Every account that should be subject to password policy control should have a
pwdPolicySubentry attribute containing the DN of a valid
pwdPolicy 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 particular 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

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.

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 unable to check the syntax it will return an error
refusing the password.

When syntax checking is enabled (see also the pwdCheckQuality attribute),
this attribute contains the minimum number of characters 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 pwdCheckQuality, either accept the
password without checking it (if pwdCheckQuality is zero (0) or one

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 specified 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.

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 access 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).

pwdCheckModule
This attribute names a user-defined loadable module that 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 compliance checks have been passed. This function will
be called according to this function prototype:

int check_password (char *pPasswd, char

The pPasswd parameter contains the clear-text user password, the
ppErrStr parameter contains a double pointer that allows the function
to return human-readable details about any error it encounters. The optional
pEntry parameter, if non-NULL, carries a pointer to the entry whose
password is being checked. If ppErrStr is NULL, then funcName
must NOT attempt to use it/them. A return value of LDAP_SUCCESS from the
called function indicates that the password is ok, any other value indicates
that the password is unacceptable. If the password is unacceptable, the server
will return an error to the client, and ppErrStr may be used to return
a human-readable textual explanation of the error. The error string must be
dynamically allocated as it will be free()'d by slapd.

OPERATIONAL ATTRIBUTES¶
The operational attributes used by the ppolicy module are stored in the user's entry. 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 slave server only affect the copy of the operational attributes on that slave and will not affect any attributes for a user's entry on the master server. Operational attribute changes resulting from authentication attempts on a master server will usually replicate to the slaves (and also overwrite any changes that originated on the slave). These behaviors are not guaranteed 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 definition. 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 exist, the ppolicy module will enforce the default password policy rules on the user associated with this authenticating DN. If there is no default, or the referenced subentry does not exist, then no policy rules will be enforced.( 1.3.6.1.4.1.42.2.27.8.1.23

This module was written in 2004 by Howard Chu of Symas Corporation with significant input from Neil Dunbar and Kartik Subbarao of Hewlett-Packard. This manual page borrows heavily and shamelessly from the specification upon which the password policy module it describes is based. This source is the IETF LDAP password policy proposal by P. Behera, L. Poitou and J. Sermersheim. The proposal is fully documented in the IETF document named draft-behera-ldap-password-policy-09.txt, written in July of 2005.
