Specify a security driver in the [SECURITY] section of libtcl.cfg.
Open Client and Open Server software use the first entry in the [SECURITY] section as the default security driver.
See Appendix B, “Configuration Files,” for reference information about security drivers and libtcl.cfg.
Optionally, to restrict the security mechanisms that a server supports:
If your application uses interfaces, add a secmech line in the server’s interfaces entry.
If your application uses a directory service, use the dscp utility to add the secmech attribute to the server’s directory service.
See Chapter 7, “Using dscp,” for information about adding information to a directory service or an interfaces file.
