Hi,

shouldn't line 292 in cgi/client.py be:

            user = self.env.get( 'REMOTE_USER', None )

instead of:

	    user = os.getenv('REMOTE_USER')

I have been writing a wrapper so that roundup can be
plugged into a quixote application and when using
client.py as a base for passing on requests I put the
remote_user that I have already validated in my
application into the environment before passing it onto
roundup.

The os.getenv() doesn't see my modified environment so
passing on the validated user was failing.
