When did HP-UX have support for ACL?

Hello,

I try to find what year HP-UX got support for ACL (Access Control List)? I know that HP-UX was the first Unix with ACL support, but it is very hard to find the information on when that occured.

So anyone here know when that did happen?

Any answers are appreciated,

Wow... too far back. I'm guessing sometime in the late eighties?? I'm thinking that if it didn't have it prior to the Apollo acquisition, it had them afterwards... but again, just a guess.
