LDAP Server

An LDAP server provides global directory services for sharing component information such as server names and connection properties.

LDAP directory services allow components to look up directory information in a network-based system. Any type of LDAP service or gateway is an LDAP server. An LDAP driver calls LDAP client libraries to establish connections to an LDAP server. The LDAP driver and client libraries define the communication protocol and content of messages exchanged between clients and servers. LDAP runs directly over the Transmission Control Protocol (TCP).

When the LDAP driver connects to the LDAP server, the server establishes the connection based on one of two authentication models:

Anonymous access – which does not require any authentication information, and is used typically for read-only privileges, or
User name and password access – which is different from the user name and password used to access Replication Server.

Replication Server uses the access information as an extension to the LDAP URL. Access information is taken from this file:

UNIX – $SYBASE/$SYBASE_OCS/config/libtcl.cfg
Windows – %SYBASE%\%SYBASE_OCS%\ini\libtcl.cfg

Replication Server uses LDAP for only authenticating server names and connection properties. You can use LDAP services in place of an Replication Server interface file. You cannot use LDAP for Replication Server user authentication.

Replication Server uses Open Client/Server libraries to connect to LDAP servers and Open Client/Server configurations and procedures to set up and maintain LDAP services. See the Replication Server Configuration Guide for your platform for directions on how to set up an LDAP directory. For detailed information about Open Client/Server LDAP support, see the Open Client Client-Library/C Reference Manual.
