yii's RBAC implementation


I’m trying to understand the yii’s RBAC implementation.

In the context of chapter 8 of the book and looking at the DDL statement of AuthAssignment table I see that primary key (itemname, userid).

My question is: how is it possible to have one user owning more than one project (or being member of more than one project)?

Thank you.

OK, problem solved according to this previous thread.

It was exactly the same problem. I searched the forum before I asked but somehow I missed this thread.
