pwdHistory, encrypted passwords and selfservice application

Hello all, I'm working on Self-service application and want to prevent user from re-using old passwords. What is correct way to chage password takin in mind password history? I guess it is: 1. Bind with special user and check if specified uid exists 2. Bind using user-supplied uid and password 3. Get password policy, history etc. and validate on selfservice-side 4. Execute LDAP modifyRequest with single item: userPassword and value of new hashed password. In my case same password gives same hash. Are there any way to force encrypted password history validation on server side? Thank you. -- Bogdan Rudas Head of Minsk IT Support Department Exadel Inc. http://www.exadel.com/ E-mail: brudas(a)exadel.com <mandrushkevich(a)exadel.com&gt; Skype ID: bogdan.rudas -- CONFIDENTIALITY NOTICE: This email and files attached to it are confidential.
