# 1. Abstract
|
|
#
|
|
# Password policy as described in this document is a set of rules that
|
|
# controls how passwords are used and administered in LDAP
|
|
# directories. In order to improve the security of LDAP directories
|
|
# and make it difficult for password cracking programs to break into
|
|
# directories, it is desirable to enforce a set of rules on password
|
|
# usage. These rules are made to ensure that users change their
|
|
# passwords periodically, passwords meet construction requirements,
|
|
# the re-use of old password is restricted, and users are locked out
|
|
# after a certain number of failed attempts.

# 4.2. Attribute Types used in the pwdPolicy ObjectClass
|
|
#
|
|
# Following are the attribute types used by the pwdPolicy object
|
|
# class.
|
|
#
|
|
# 4.2.1. pwdAttribute
|
|
#
|
|
# This holds the name of the attribute to which the password policy is
|
|
# applied. For example, the password policy may be applied to the
|
|
# userPassword attribute.

# 4.3. Attribute Types for Password Policy State Information
|
|
#
|
|
# Password policy state information must be maintained for each user.
|
|
# The information is located in each user entry as a set of
|
|
# operational attributes. These operational attributes are:
|
|
# pwdChangedTime, pwdAccountLockedTime, pwdExpirationWarned,
|
|
# pwdFailureTime, pwdHistory, pwdGraceUseTime, pwdReset,
|
|
# pwdPolicySubEntry.
|
|
#
|
|
# 4.3.1. Password Policy State Attribute Option
|
|
#
|
|
# Since the password policy could apply to several attributes used to
|
|
# store passwords, each of the above operational attributes must have
|
|
# an option to specify which pwdAttribute is applies to.
|
|
# The password policy option is defined as the following:
|
|
# pwd-<passwordAttribute>
|
|
#
|
|
# where passwordAttribute a string following the OID syntax
|
|
# (1.3.6.1.4.1.1466.115.121.1.38). The attribute type descriptor
|
|
# (short name) MUST be used.
|
|
#
|
|
# For example, if the pwdPolicy object has for pwdAttribute
|
|
# "userPassword" then the pwdChangedTime operational attribute, in a
|
|
# user entry, will be:
|
|
# pwdChangedTime;pwd-userPassword: 20000103121520Z
|
|
#
|
|
# This attribute option follows sub-typing semantics. If a client
|
|
# requests a password policy state attribute to be returned in a
|
|
# search operation, and does not specify an option, all subtypes of
|
|
# that policy state attribute are returned.
|
|
#
|
|
# 4.3.2. pwdChangedTime
|
|
#
|
|
# This attribute specifies the last time the entry's password was
|
|
# changed. This is used by the password expiration policy. If this
|
|
# attribute does not exist, the password will never expire.
