Authentication Failed

[maurer@…]

I created a new TRAC site and I can not login. The site comes up, everything appears to be ok but then I receive the error "Authentication information not available." and

Python traceback
Traceback (most recent call last):
  File "/usr/lib/python2.3/site-packages/trac/web/cgi_frontend.py", line 131, in run
    dispatch_request(req.path_info, req, env)
  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 139, in dispatch_request
    dispatcher.dispatch(req)

  File "/usr/lib/python2.3/site-packages/trac/web/auth.py", line 102, in _do_login
    assert req.remote_user, 'Authentication information not available.'
AssertionError: Authentication information not available.

What can I do now to fix this? The users and group have been defined in access.group and access.user
