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 SAP ASE. Two examples of directory services are Registry, and Distributed Computing Environment (DCE).
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, SAP ASE 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, see the configuration documentation for your platform for detailed information about configuring for directory services.
