Hello,
I noticed that if using simple access provider and having non-existing
group or user in access/deny list then access will be denied and "su:
System error" will be printed.
I think it's OK to simply skip non-existing objects on allow_list.
I'm not so sure what to do in case of deny lists. Should we also just
skip them or should we deny the user and print more appropriate message
("su: Permission denied")?
Thanks,
