ACL's allow the administrator (or the owner in some cases, depending on
the OS) to define access permissions on a user granularity. What this
means, in plain English, is that I can make a file readable to all, and
explicitly deny access to any user or group I wish, or vice versa.
ACLs, in theory, refer to any object that has access permissions, in Linux
those would be files (everything under userland Unix can be represented as
a file last I looked.), in NT those would be system objects.
The unices that support ACL's are AFAIK DG-UX, AIX, and HP-UX, at
least officially. NT supports ACLs. I believe I've seen a Linux ACL patch,
I just don't recall where. It's, ofcourse, a kernel patch, so start by
looking at kernel patch repositories.
ACLs AFAIK are not POSIX compliant, but I might be, and I'm probably, very
wrong at this. Feel free to correct me.
