I am having problems with the users-admin utility.

When ever I try to 'unlock' it so that I can add a new user
or change user settings, I get the following error message:

could not authenticate, an unexpected eror occured

In the xsession errors file it says that users-admin had ar
error code of 6091 and something about the server program
was not responding.

This computer is not running on a net work at this time.
