This is the strangest thing I've ever seen. I have a SharePoint 2007 team site which has it's own unique permissions, and I am the only person with Full Control on the site, all other users are either read, append or contributor.
A user reported to me today that they no longer had access to the site, I checked the site level permissions and saw that the permissions were no longer unique, but were inheriting from the parent site. I know for sure I did not do this, I've been
administering our SharePoint environments for the past 7 years, and was nowhere near the site within the the past couple weeks. Nobody else would have rights to change the permissions to re-inherit from it's parent site.
What on earth could have caused this? I have no idea on where to start looking, or what to even search for to see if this has happened to anyone else.
Any help would be most appreciated!
