Subject Re: [PATCH] mod_authnz_ldap and satisfy all
Date Wed, 07 Sep 2005 16:02:44 GMT
  +1 in concept as well but it seems that this should be implemented at
some lower level so that we don't have to touch each authz module to
teach them how to deal with the satisfy directive.  

The problem is that the auth_checker hook is defined as
AP_IMPLEMENT_HOOK_RUN_FIRST meaning that each registered hook will be
called in turn until something other than DECLINE is returned.  If
something other than DECLINE is returned then the appropriate action
takes place.  Either authorization succeeds or fails with a specific
error.  Satisfy All would need to change the behavior of the hook so
that each registered hook is called in turn as long as OK or DECLINE is
returned.  Then if something other than OK or DECLINE is returned, the
authorization fails.  This would probably require defining a new type of
hook that would be defined as AP_IMPLEMENT_HOOK_RUN_ALL.  

At this point I am not sure how to make that happen without drastically
altering the way authorization is currently configured and works. 
Currently Satisfy All | Any is very specific in how it is implemented
inside of ap_process_request_internal().  It's purpose is to satisfy
access control vs. (authentication and authorization).  This would also
need to be changed or use something other than the Satisfy directive.
