Configuring an LDAP server

User authentication for Lightweight Directory Access Protocol (LDAP) supports the Secure Sockets Layer/Transport Layer Security (SSL/TLS) protocol, providing secure data transmission between Adaptive Server and an LDAP server.

1. Make sure that all trusted root certificates are located in the same file.

   After you define the trusted servers, Adaptive Server configures a secure connection, where servername is the name of the current Adaptive Server. If you:

   • Have defined $SYBASE_CERTDIR, Adaptive Server loads certificates from $SYBASE_CERTDIR/servername.txt (for UNIX) or %SYBASE_CERTDIR%\servername.txt (for Windows).

   • Have not defined $SYBASE_CERTDIR, Adaptive Server loads certificates from $SYBASE/$SYBASE_ASE/certificates/servername.txt (for UNIX) or %SYBASE%\%SYBASE_ASE%\certificates\servername.txt (for Windows).

2. Restart Adaptive Server to change the trusted root certificate file.

3. Use sp_ldapadmin, specifying ldaps:// URLs instead of ldap:// URLs, to establish a secure connection to a secure port of the LDAP server.

4. Establish a TLS session over a plain TCP connection:

   sp_ldapadmin 'starttls_on_primary', {true | false}
   

   or

   sp_ldapadmin 'starttls_on_secondary', {true | false}
