Trustee is a member of a group that provides feature rights to members (scan, import, search, print, export, edit text, move entry, process, extended properties, delete, migrate documents). A folder in our repository has inherited access rights (browse, read) and this group is included on the list of Trustees with those access rights ("Show inherited rights"). Access to this folder is further controlled by a security tag - without the tag, users don't have access to the contents of the folder.
It's normally a quick and easy task to simply apply the tag from within the Properties dialog box for a user, but this time I'm getting the "The specified object is already a member of this collection" error. When I view the list of trustees assigned to the tag, this user is not on the list.
It sounds like the error is telling me that the user already has access to the folder and its contents, but he doesn't.
We're using LF Rio, version 9.0.3.798.
