Use the libtcl.cfg files to specify an LDAP server name, port number, DIT base, user name, and password to connect to an LDAP server.
In its simplest form on 32-bit LDAP drivers, the libtcl.cfg file is in this format:
[DIRECTORY] ldap=libsybdldap.dll
When an LDAP server is specified in the libtcl.cfg file, the server information is accessible only from the LDAP server. Adaptive Server ignores the interfaces file. Open Client and Open Server applications that use the -i option at start-up override the libtcl.cfg file and use the interfaces file.
