If the client is a Linux box, make sure you have this set
in /etc/ldap.conf:

pam_password clear

Otherwise what is being passed to the directory server is the hashed
password, and the password history comparison will not find a match.
The DS will take the clear password, and encrypt it with matching
salts/method to see if the new password matches what's in the history.

You will also want to enable LDAPS or SSL/TLS so your passwords are not
going across the wire in the clear.

Hope this helps,
