A directory stores information as directory entries and associates a logical name with each entry. Each directory entry contains information about some network entity, such as a user, a server, or a printer.
A directory service (sometimes called a naming service) manages creation, modification, and retrieval of directory entries.
By default, Client-Library uses the Sybase interfaces file as the directory source. Sybase also provides directory drivers for several network-based directory services such as DCE’s Cell Directory Service (CDS) and the Windows Registry service. For information about the directory drivers that are available on your platform, see the Open Client and Server Configuration Guide for Microsoft Windows and Open Client and Server Configuration Guide for UNIX.
