A method for integrating a network application with different directory servers, each server having a different schema. The method includes providing meta-data specifying directory servers available to the application and a table mapping attributes utilized by the network application with attribute names used by the directory servers available to the application. The method further includes identifying in the table the directory server attribute name corresponding to an attribute requested by the application when the application runs. A request containing the identified directory server attribute name is sent to the corresponding directory server and information is received in response to the request.
