Hi Johnny,
let me help you.
I will try to show steps I do to find it in WIKI myself:
1) I go to Valentina WIKI:
http://www.valentina-db.com/docs/dokuwiki/v5/
2) in left top SEARCH field typing
ACL and do search. Result is:
http://goo.gl/hNlk5o
Only one page found:
http://goo.gl/zjl0AJ
=============
* Also I have check search of "Access Control List".
In this way also page is found.
* Let me know if any more questions about ACL.
I can plug Ivan for this issue to help.
