The Password Policy control is based the IETF password policy proposal 
for LDAP. The following URLs provide more detail on it:


Essentially the code I've provided allows users of JLDAP send password 
policy request control messages and interpret the directory server 
responses. It can be used in the following instances:

* At bind time where the directory server can indicate whether the 
user's account is about to expire, has expired, or is locked.
   * If the account is about to expire, how long before this occurs.
   * If the account has expired, how many grace logins are left before 
the account is locked out.
* At password reset time where the directory server can indicate whether 
the new password meets password policy requirements including:
   * Whether the password is strong enough.
   * Whether the new password set is one that has already been used.
These and more are described in the URLs I have provided.

Although it is an expired draft, it is supported by OpenLDAP (in slapd 
via the slapo-ppolicy overlay and is also supported by the ldapsearch 
client). It is also supported by the following LDAP servers (there may 
be more but these are the ones I do use):

CA/eTrust directory
SunONE directory
IBM Tivoli directory server

The functionality provided by the code I've written is also available in 
other programming languages (Perl via Net::LDAP and in other Java LDAP
