Description of problem:
I'm trying to use gssapi to log into a test web server.  I kinit as user from
terminal window then run firefox.  I get the user/password ipsilon login screen
with a section on the right for "Other authentication methods:" which shows a
link for "gssapi",  Clicking on this link I get the following error on screen:
"""
404 - Not Found
The path '/idp/login/gssapi/gssapi/negotiate' was not found.
If you think this is an error, contact the server administrator to resolve the
problem.
"""
Rob noticed the double gssapi in the path which is the problem.
