Hi
• LDAP Search-provides a COM server object that performs queries on any LDAP-compliant directory server and returns the output in the Cisco IP Phones Services XML data format. LDAP Search enables you to search by:
Full name ,First name,Last name, Phone number, E-mail, LDAP distinguished name (DN), LDAP relative distinguished name (RDN). Hope you have tried the LDAP Search COM Server- which enables you to retrieve information from a LDAP directory server and send it in the correct XML format to the Cisco IP Phone .
Please refer https://communities.cisco.com/docs/DOC-49767
and CUCM Corporate Directory Shows Incorrect Search Result
Thanks and Regards,
