Hello!
Anybody try integrates phpGACL class into Xoops?

I create several XOOPS modules, which are using by employees who work in different departments. It's my first project that big. And manage of users and permissions became a bit difficult.
Users from one department can't view/edit values assigned to different one. There are also groups of users (f.e. management team) without restrictions depending on department. Etc., etc...
Now I have one group for each module and each department. In addition inside modules I appoint users with extra/special rights. It's not too flexible.

phpGACL implements subgroups and allow set rights even to single user. And all of this in one place. I think that managing of users and groups permissions with phpGACL will be easier.
Or maybe is there a possibility to implement subgroups in xoops? Any other idea?
