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. +# +# [trimmed] +# +# +# 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.
