I have a user who is listed only once in our AD, only comes up once in the user selection search, however she is listed twice when looking at a user field within a the datasheet view.
Is there any way to purge this duplicate? They are distinctly different in the eyes of SharePoint as can be seen by the lookup ID in the second part of the image below.
We are using claims based auth.
Updates: It is 2010, and I am 100% positive there is only 1 AD account for this person.
Updates 2: I just checked and sure enough an old, non-claims account was listed for her:
I guess it's a matter of deleting her old account from the site collection?
