Patent ID: 7840615

Claim:
A method to provide interoperation of directory services resident on a computer system comprising: on a computer system with a first directory service resident and managing a network, installing a second directory service resident on a network computer system, selected application-specific schema changes being prohibited in said first directory service and allowed in said second directory service; starting a directory service access library to handle client application information requests from directory-enabled applications and managing access as a front end access point to the first and the second directory services, the directory service access library directing the client application information requests to the first directory service and selectively redirecting the client application information requests to the second directory service when requested information is associated with the second directory service, such that the first and the second directory services interoperate with one another on the network; selectively migrating data from said second directory service to said first directory service, wherein selectively migrating data comprises removing installed instance entries in the first directory service indicating the presence of the second service and extending said schema extensions to the first directory service; and selectively disabling said second directory service, said directory service access library being prevented from detecting said disabled second directory service, wherein disabling said second directory service comprises disabling publishing mode for the second directory service.
