I use realtime to connect ldap server at lync 
But When I query the ldap , I get below error in full log .
I expect the ldap query will get back something according input givename=William .
The REALTiME function cannot retrevie the givename from lync and output null.
There is this key/attribute in lync server .....
There is openration error .
The lync ldap server is working and I can use the filter (&(objectClass=user)(givenname=William)) to get the result by
php ldap_Search .. it is work .
Please advice what is wrong in asterisk I use asterisk 1.8.11 ...
