I have opened the 'Share Documents' on a client system using two domain
user-IDs, once simultaneously and once one after the other.
The user IDs are 'User1' and 'User2'.
Now, if I login as 'User2' and create a new document, the 'Modified By'
column shows 'User1'.
But when I check-out, the 'Checked Out To' column shows 'User2'.
I could not understand this clash. I checked by using just single
browser with only 'User2' account. Still the problem continues.
Please note that 'User1' is part of 'Administrator' site group and
'User2' is part of 'Contributor' site group.
