Configure security options using the ocs.cfg and libtcl.cfg files.
For a connection, use ocs.cfg to set directory and security properties. Edit libtcl.cfg to load security and directory service drivers.
The DBD::SybaseASE driver does not currently have APIs to support the security and directory services from within the Perl application script. Currently, there is no possibility to enable security options through the DSN.
For more information, see Configuration Files in the Open Client and Open Server Configuration Guide for UNIX.
