A directory service manages the creation, modification, and retrieval of network service information. Directory services are provided by platform or third-party vendors and must be purchased and installed separately from Adaptive Server. Two examples of directory services are NT Registry and Distributed Computing Environment (DCE).
The $SYBASE/config/libtcl.cfg file is a Sybase-supplied configuration file used by servers and clients to determine:
Which directory service to use, and
The location of the specified directory service driver.
If no directory services are installed or listed in the libtcl.cfg file, Adaptive Server defaults to the interfaces file for obtaining network service information.
The System Administrator must modify the libtcl.cfg file as appropriate for the operating environment.
Some directory services are specific to a given platform; others can be used on several different platforms. Because of the platform-specific nature of directory services, refer to the configuration documentation for your platform for detailed information on configuring for directory services.
