#Abstract
|
|
#
|
|
# Password policy as described in this document is a set of rules that
|
|
# controls how passwords are used and administered in Lightweight
|
|
# Directory Access Protocol (LDAP) based 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
|
|
#
|
|
# [trimmed]
|
|
#
|
|
#5. Schema used for Password Policy
|
|
#
|
|
# The schema elements defined here fall into two general categories. A
|
|
# password policy object class is defined which contains a set of
|
|
# administrative password policy attributes, and a set of operational
|
|
# attributes are defined that hold general password policy state
|
|
# information for each user.
|
|
#
|
|
#5.2 Attribute Types used in the pwdPolicy ObjectClass
|
|
#
|
|
# Following are the attribute types used by the pwdPolicy object class.
|
|
#
|
|
#5.2.1 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.

#5.3 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, pwdFailureTime, pwdHistory, pwdGraceUseTime,
|
|
# pwdReset, pwdPolicySubEntry.
|
|
#
|
|
#5.3.1 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 it 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.
|
|
#
|
|
#5.3.2 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.
