[mod_python] populate user name in login prompt (for session)

Hey all

My site requires a password to be accessed...I do not
really care what the user name is.  Thus, I would like
to populate the login prompt with a default name, like
user or admin, etc.  Is this possible or is it
possible to just prompt for a password and nothing
else?  I have included the code I am using (this code
was clipped from an earlier post and modified).

Thanks

Rob

def __auth__(req, user, passwd):

     # removed check for user=USER

     if passwd == PASS:
             # user has successfully authenticated
             sess = Session(req)

             if sess.has_key('max_inactive'):
                     # this is an existing session

                     # check length of inactivity
                     elapsed = time.time() -
sess['last']

                     # reset timer for next request
                     sess['last'] = time.time()
                     sess.save()

                     # compare elapsed inactivity to
maximum allowed
                     if elapsed >
sess['max_inactive']:
                             # it's been too long

                             # uncomment to delete
session (optional)
                             sess.delete()

                             # force user to
reauthenticate
                             return 0
                     else:
                             # still within time limit
                             #
req.write("Authorized.\n\n")

                             # allow user to continue
                             return 1
             else:
                     # this must be a new session, so
set session variables

                     # set maximum inactivity allowed,
in seconds
                     sess['max_inactive'] = 500

                     # initialize timer
                     sess['last'] = time.time()

                     sess.save()

                     # do new session stuff here
                     # req.write("Session
started.\n\n")

                     # allow user to continue
                     return 1
     else:
             # wrong user or password, force user to
reauthenticate
             return 0
