#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.

attributetype ( 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 )

#5.2.2  pwdMinAge
#
#   This attribute holds the number of seconds that must elapse between
#   modifications to the password.  If this attribute is not present, 0
#   seconds is assumed.

attributetype ( 1.3.6.1.4.1.42.2.27.8.1.2

      ORDERING integerOrderingMatch
      SYNTAX 1.3.6.1.4.1.1466.115.121.1.27
      SINGLE-VALUE )

#5.2.3  pwdMaxAge
#
#   This attribute holds the number of seconds after which a modified
#   password will expire.
#
#   If this attribute is not present, or if the value is 0 the password
#   does not expire.  If not 0, the value must be greater than or equal
#   to the value of the pwdMinAge.

attributetype ( 1.3.6.1.4.1.42.2.27.8.1.3
      NAME 'pwdMaxAge'

      ORDERING integerOrderingMatch
      SYNTAX 1.3.6.1.4.1.1466.115.121.1.27
      SINGLE-VALUE )

#5.2.4  pwdInHistory
#
#   This attribute specifies the maximum number of used passwords stored
#   in the pwdHistory attribute.
#
#   If this attribute is not present, or if the value is 0, used
#   passwords are not stored in the pwdHistory attribute and thus may be
#   reused.

attributetype ( 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 )

#5.2.5  pwdCheckQuality
#
#   {TODO: Consider changing the syntax to OID.  Each OID will list a
#   quality rule (like min len, # of special characters, etc).  These
#   rules can be specified outsid ethis document.}
#
#   {TODO: Note that even though this is meant to be a check that happens
#   during password modification, it may also be allowed to happen during
#   authN.  This is useful for situations where the password is encrypted
#   when modified, but decrypted when used to authN.}
#
#   This attribute indicates how the password quality will be verified
#   while being modified or added.  If this attribute is not present, or
#   if the value is '0', quality checking will not be enforced.  A value
#   of '1' indicates that the server will check the quality, and if the
#   server is unable to check it (due to a hashed password or other
#   reasons) it will be accepted.  A value of '2' indicates that the
#   server will check the quality, and if the server is unable to verify
#   it, it will return an error refusing the password.

      SINGLE-VALUE )

#5.2.6  pwdMinLength
#
#   When quality checking is enabled, this attribute holds the minimum
#   number of characters that must be used in a password.  If this
#   attribute is not present, no minimum password length will be
#   enforced.  If the server is unable to check the length (due to a
#   hashed password or otherwise), the server will, depending on the
#   value of the pwdCheckQuality attribute, either accept the password
#   without checking it ('0' or '1') or refuse it ('2').

#5.2.7  pwdExpireWarning
#
#   This attribute specifies the maximum number of seconds before a
#   password is due to expire that expiration warning messages will be
#   returned to an authenticating user.
#
#   If this attribute is not present, or if the value is 0 no warnings
#   will be returned.  If not 0, the value must be smaller than the value
#   of the pwdMaxAge attribute.

#5.2.8  pwdGraceAuthNLimit
#
#   This attribute specifies the number of times an expired password can
#   be used to authenticate.  If this attribute is not present or if the
#   value is 0, authentication will fail.

#5.2.9  pwdLockout
#
#   This attribute indicates, when its value is "TRUE", that the password
#   may not be used to authenticate after a specified number of
#   consecutive failed bind attempts.  The maximum number of consecutive
#   failed bind attempts is specified in pwdMaxFailure.
#
#   If this attribute is not present, or if the value is "FALSE", the
#   password may be used to authenticate when the number of failed bind
#   attempts has been reached.

#5.2.10  pwdLockoutDuration
#
#   This attribute holds the number of seconds that the password cannot
#   be used to authenticate due to too many failed bind attempts.  If
#   this attribute is not present, or if the value is 0 the password
#   cannot be used to authenticate until reset by a password
#   administrator.

#5.2.11  pwdMaxFailure
#
#   This attribute specifies the number of consecutive failed bind
#   attempts after which the password may not be used to authenticate.
#   If this attribute is not present, or if the value is 0, this policy
#   is not checked, and the value of pwdLockout will be ignored.

#5.2.12  pwdFailureCountInterval
#
#   This attribute holds the number of seconds after which the password
#   failures are purged from the failure counter, even though no
#   successful authentication occurred.
#
#   If this attribute is not present, or if its value is 0, the failure
#   counter is only reset by a successful authentication.

#5.2.13  pwdMustChange
#
#   This attribute specifies with a value of "TRUE" that users must
#   change their passwords when they first bind to the directory after a
#   password is set or reset by a password administrator.  If this
#   attribute is not present, or if the value is "FALSE", users are not
#   required to change their password upon binding after the password
#   administrator sets or resets the password.  This attribute is not set
#   due to any actions specified by this document, it is typically set by
#   a password administrator after resetting a user's password.

#5.2.14  pwdAllowUserChange
#
#   This attribute indicates whether users can change their own
#   passwords, although the change operation is still subject to access
#   control.  If this attribute is not present, a value of "TRUE" is
#   assumed.  This attribute is intended to be used in the absense of an
#   access control mechanism.

#
#   This attribute specifies whether or not the existing password must be
#   sent along with the new password when being changed.  If this
#   attribute is not present, a "FALSE" value is assumed.

# pwdCheckModule
#
#    This attribute names a user-defined loadable module that provides
#    a check_password() function. If pwdCheckQuality is set to '1' or '2'
#    this function will be called after all of the internal password
#    quality checks have been passed. The function has this prototype:
#
#    int check_password( char *password, char **errormessage, void *arg )
#
#    The function should return LDAP_SUCCESS for a valid password.

#5.1  The pwdPolicy Object Class
#
#   This object class contains the attributes defining a password policy
#   in effect for a set of users.  Section 10 describes the
#   administration of this object, and the relationship between it and
#   particular objects.

#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.

#
#5.3.3  pwdAccountLockedTime
#
#   This attribute holds the time that the user's account was locked.  A
#   locked account means that the password may no longer be used to
#   authenticate.  A 000001010000Z value means that the account has been
#   locked permanently, and that only a password administrator can unlock
#   the account.

#5.3.5  pwdHistory
#
#   This attribute holds a history of previously used passwords.  Values
#   of this attribute are transmitted in string format as given by the
#   following ABNF:
#
#   pwdHistory = time "#" syntaxOID "#" length "#" data
#

#                              ; dotted-decimal OID that defines the
#                              ; syntax used to store the password.
#                              ; numericoid is described in 4.1
#                              ; of [RFC2252].

#
#   data       = <octets representing the password in the format
#                 specified by syntaxOID>.
#
#   This format allows the server to store, and transmit a history of
