You _cannot_ read the unicodePwd attribute (where the actual passwd
lies) from AD.  It can only be written to, and then only under certain
conditions (SSL/TLS connection, and if not written by an admin, then a
delete/add must be performed in the same operation).

This is why you should use ntlm_auth w/PEAP for AD auth.  You could be
able to auth against LDAP (PAP) in a TTLS situation (not tried that yet,
so I don't know how it would work), but you will never retrieve the
unicodePwd attribute.

Hope this helps.
