CHAPTER 6 Using the Lightweight Directory Access Protocol as a Directory Service

In the example above, the entry describes an Adaptive Server named “foobar” listening on a TCP connection with a port number of 5000. This entity also specifies a retry count of 12 (times) and a retry delay of 30 (seconds). Once a client has found an address where a server responds, the login dialog between the client and the server begins.

You can find a complete list of Sybase’s LDAP directory schema in UNIX $SYBASE/$SYBASE_OCS/config.

In the same directory, there is also a file called sybase-schema.conf, which contains the same schema, but uses a Netscape-specific syntax.

Since LDAP supports multiple entries for each attribute, each address attribute must contain the address of a single server, including protocol, access type, and address. See sybaseAddress in Table 6-2.

For example, this is an LDAP entry for an Windows server listening on two addresses, with different connection protocols:

sybaseAddress = TCP#1#TOEJAM 4444 sybaseAddress = NAMEPIPE#1#\pipe\sybase\query

Note Each entry in the address field is separated by the # character.

You can edit these entries with dsedit. See “Adding a server to the directory services” on page 76.

To ensure cross-platform compatibility for all Sybase products, the protocol and address attribute fields should be in a platform- and product-independent format.

The libtcl*.cfg file

You use the libtcl*.cfg file to specify the LDAP server name, port number, DIT base, user name, and password to authenticate the connection to an LDAP server.

The purpose of the libtcl*.cfg file is to provide configuration information such as driver, directory, and security services for Open Client/Open Server and Open Client/Open Server-based applications. 32-bit utilities such as dsedit and srvbuild, look up the libtcl.cfg, while 64-bit applications use the libtcl64.cfg file for configuration information
