>From the POD It authenticates users in two steps:

1) A search of the directory is performed, looking for a user object that

   matches the username you pass.  This is done with the bind credentials

   supplied in the "binddn" and "bindpw" configuration options.

2) If that object is found, we then re-bind to the directory as that

   Assuming this is successful, the user is Authenticated.

And the actual check password code:

$self->store->ldap_bind( undef, $self->ldap_entry->dn, $password,

        'forauth' );

Notice the rebind.

So it does not try to "retrieve the crypted password",  it does bind (anon
or by authorized service account if set in binddn and bindpw) to the ldap
server, Next it grabs the user's dn from a search on that bind.  Finally to
authenticate it actually binds to the ldap server as that user's dn.  This
works well against AD (I use it),  I don't understand what deficiency you
are trying to fix with your patch.
