I have some strange behaviour happening in SharePoint 2010, which I believe is something to with Impersonation but I'm not entirely sure.
I'm not sure how to word this, so I'll do it like this:
- A user (User A) is logged into Windows.
- The user (still User A) opens up a SharePoint 2010 site and then signs in under a different user (User B).
- The user (now logged in as User B in SharePoint) edits a Word document which is required to be checked out.
- SharePoint 2010 checks out the document as User B but when Word opens up a message is displayed saying 'This document is checked out by User B'.
The Word document should be able to be edited because the user context from SharePoint sent to Word should be as User B not User A. It seems that Word is still opening up as User A and because the document is actually checked out to User B it can't be edited.
(User A and User B are both AD accounts)
I'm not sure if this is a SharePoint configration issue or if our network is somehow configured so impersonation of an AD account isn't allowed (I'm not even sure that's possible).
Has anyone seen or had this problem before?
Also, the same thing happens when opening Explorer View. If I'm logged into Windows as User A but logged into SharePoint as User B when I open up Explorer View I cannot access the view because WebDAV thinks I am User A.
I hope this makes sense? It's pretty difficuly to explain...
