But that's the problem - that would mean reading the entire POSIX
ACL list and doing the match for every single file in a directory
listing. That's just too slow.
Currently we allow the DOS attributes to be stored in an EA, and
will read that (which is also an extra metadata access per file
on a directory listing) but we don't do any more than that.

Precisely. This is something that isn't new and has been in Samba
a long time. I don't think it's a critical bug that needs urgent
code changes - unlike the ACL issues which were bugs in new
