LDAP user edit user binding

This module is only helpful if you are using LDAP module and have binding method set to "Bind with Users Credentials: Use user's entered credentials to bind to LDAP.".

This module adds an LDAP password field to user profile form. When submitting, it tries to use that password, and the user's LDAP DN, to bind to LDAP server. If successful, then LDAP can use those same credentials later (in ldap_user_user_update()) to push updated user data to LDAP server.
