Where does the People Picker (used with a field like "Person or Group") get its information? I thought it was User Profiles, but apparently not.
We have a user whose last name changed. The fields in Active Directory were updated - her AD account was renamed from MYDOMAIN\tsmith to MYDOMAIN\tjones and her display name was changed from "T Smith" to "T Jones".
I did a User Profile incremental sync, and her user profile now shows her correct name in SharePoint. (SP 2010 SP1)
When someone tries to use the People Picker in a Person or Group field (for example), if I search on her old last name (smith) it does not find her. That's correct.
If I search on her new last name (jones), it does find her. That's correct.
But the "Display Name" column in the People Picker window still shows her old last name. The "Account Name" column in there shows her renamed account name (MYDOMAIN\tjones), but the Display Name is incorrect.
How does it get the data for the "Display Name" column? Is it cached? How do I get that updated?
