A system for handling an LDAP service request to an LDAP server for an LDAP service comprises a client program executable on a client system and a handler program executable on a handler system. The client program is operable to generate LDAP service request data corresponding to the LDAP service and provide the LDAP service request data for transmission from the client system, and further operable to receive LDAP service reply data in response to the LDAP service request data. The handler program is operable to receive the LDAP service request data transmitted from the client system and execute the LDAP service request to the LDAP server, receive LDAP service reply data from the LDAP server during one or more passes, and upon completion of the LDAP service, provide the LDAP service reply data for transmission to the client system in a single pass.
