We have a Named Access Control List we call "Edit for Named Access, Read only all others". The settings are exactly that. "Named User" has "Delete, Edit, Read" permission. "All internal users" have "Read" permission.
We have a document that has permissions of this Named Access Control List.
The document class does not have "Automatic Permissions: Restrict the permissions of objects that refer to this class" set. There is no workflow default for new objects of this class.
When I click on the permissions to view the Effective permissions, the list of users that have "Read, Edit, Delete" access do not match the current list of users that have Named User licenses. Some of the users are old users that have since had their license removed and accounts disabled. It looks like something isn't processing the live list of licenses. I'm at a loss where to look next.
