Configuring libtcl.cfg for LDAP

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.

The default libtcl.cfg file is located in %SYBASE%|%SYBASE_OCS%\ini.

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.

1. Configure the libtcl.cfg file to use directory services—use any standard ASCII text editor to:

   • Remove the semicolon (;) comment markers from the beginning of the LDAP URL lines in the libtcl.cfg file under the [DIRECTORY] entry.

   • Add the LDAP URL under the [DIRECTORY] entry. See the Configuration Guide for supported LDAP URL values.

   WARNING! Enter the LDAP URL on a single line.

   ldap=libsybdldap.dll
   ldap://host:port/ditbase??scope??
   bindname=username?password
   

   For example:

   [DIRECTORY] 
   ldap=libsybdldap.dll
   ldap://huey:11389/dc=sybase,dc=com??one??
   bindname=cn=Manager,dc=sybase,dc=com?secret
   

2. Verify that the appropriate environment variable points to the required third-party libraries. The Netscape LDAP SDK libraries are located in %SYBASE%\%SYBASE_OCS%\dll

   The Windows PATH environment variable must include this directory.

3. Use dsedit to add a server to the directory service:

   1. From Windows, select Start | Programs | Sybase | Connectivity | Open Client Directory Service Editor.

   2. Select LDAP from the list of servers, and click OK.

   3. Click Add New Server Entry.

   4. Enter:

      • The server name – this is required.

      • Security mechanism – optional. A list of security mechanism OIDs are located in %SYBASE%\ini\objectid.dat.

   5. Click Add New Network Transport.

      • Select the transport type

      • Enter the host name

      • Enter the port number

   6. Click OK twice to exit the dsedit utility.
