I am looking for a program to provide additional / optional protection
mechanism over/beside Unix permission modes.

I believe that I have seen something out there on the net in the past.

What I have in mind is a program which would read a user-provided
database of 'groups' and determine whether the user in question was
permitted to access a particular file.  There would have to be
various security features built into the software, but this would
allow a project or individual maintain some level of control wihtout
having to go thru adding groups to a system group file.  Perhaps
someone remembers seeing something like this?
