Here is an interesting situation. I have employees that belong to a SharePoint Owners Group. That group has "Full Control" over a site and all its components - doc library, pages library, lists, etc.
We are running SP2010 Enterprise. This is all SharePoint groups, no AD groups are involved at all. However, the employees are coming in through AD and the User Profile Service.
The members of the "Owners Group" can perform all of the standard site owner functions but they can not edit pages in a Pages library.
The Pages library inherits permissions from the parent site. The owners group is displayed in the Pages library permissions settings as having Full Control (inherited from parent).
Check in/out and version control are turned on. The page in question is NOT checked out.
This phenominon is happening to more than one Owners Group across our intranet.
Thoughts? I am really stumped.....
