The security authenticator is necessary for secure DCAF only. It authenticates sessions with secure targets. The security authenticator also gives access to secure targets based on security profiles for authorized controllers that it receives from the security administrator.

Install the security authenticator on an OS/2 target on the same LAN. Install it either on the security administrator workstation or on the secure OS/2 target workstation, so that it can receive security information from the security administrator.

If you install the security administrator on the LAN, you can install the security authenticator on the same workstation. Install at least one security authenticator for each logical LAN in your network.
