In all the modules the phases are seperate, because they all hook
check_user_id and check_user_access.  There is no way however to
determine the group a user is in from check_user_id in a non module
specific way.  I would like _that_ to be possible, since now, the
authz part (check_user_access) is doing stuff auth should do: checking
for group membership.

Yes, but I don't see that as a problem.  Right now, the same is
true for the FakeBasicAuth feature of mod_ssl which provides a one line
DN as the username.
