I'm curious about the "issue" in the title. Let's assume that I have a document with groups "A", "B" assigned to it. Then once I log in, as the user of group "C" in the APP, that document will show up or hidden automatically by FileNet Content Engine logic?
What you think based on your experience. By past experience, if I recall it does that thing.
The solution to my issue was. Working with Custom Object which contains "Security Proxy" class with security ldap configurations.
So, in order to change inheritance of an document class, I had to replace an old security proxy with a new one. And uola...that did a trick.
