All Authentication Mechanisms Are Disabled and No-one Can Log In

If a Secure Global Desktop Administrator accidentally disables all authentication mechanisms, no-one can log in to SGD, even the UNIX root user.

You solve this problem as follows:

1. Become superuser (root) on an SGD host.
2. Enable a UNIX system authentication mechanism from the command line.

   Use the following command:

   # tarantella config edit --login-ens 1

3. Log in to SGD Administration Console with the user name Administrator and the UNIX root user's password.
4. On the Global Settings » Secure Global Desktop Authentication tab, reconfigure user authentication.
