One is disabled.  In our environment, I want the server to be the
primary DHCP server and also serve thin clients located in different
parts of the school.  I took out the bridge interface to see if it made
a difference.  Authentication still failed.  If I leave everything in
the default setting, authentication works fine.  What gets affected with
the IP change that has to do with authentication?

You have only a single ethernet interface on this box?
