additional restriction on the rule, isn't it?
Still, this beats creating deny rules. Every single time we added
rules in any form or shape to sssd we ended up regretting that decision
after some time..

Is the problem really evaluating the rule or finding the rule?
I thought our biggest worry is that the rule will not be seen at all.
And if we require all rules to pass, failure to find the last rule
(and evaluate) when all previous have passed, will allow the access.
To me, requiring all ruless to pass means that each additional rule
is an effective deny on anything it does not match. Yes, if we
are aware of the rule existence, we deny the access at worse, but
if we miss the rule existence altogether, we've just granted access
we were not supposed to grant.
