Open Client and Open Server software uses a directory driver to retrieve information from a directory service.
A directory driver is a dynamically-linked Sybase library that provides Open Client and Open Server software with a generic interface to a specific directory service. Sybase provides a directory driver for each supported directory service.
Directory drivers are listed in the libtcl.cfg file. See “The libtcl.cfg and libtcl64.cfg files” for reference information about directory drivers and libtcl.cfg.
