I am working for the support of a SharePoint 2010 intranet.
The User Profile Application Service performs an incremental synchronization each day.
The UPAS retrieves user profiles from an Active Directory.
Each SharePoint user profile has several properties and one of them is UserName.
The UserName property is mapped to the sAMAccountName AD property.
Active Directory user accounts will be migrated soon.
Some tests are performed in a preproduction environment to check users can still use the SP intranet after migration.
I have asked an AD administrator to migrate one AD user account for a test.
The administrator has created the new user account in AD and he has deactivated the old user account.
Old user account's sAMAccountName : sharept2
New user account's sAMAccountName : TestUser2.Sharepoint
The AD administrator has also migrated the corresponding SP user by executing the stsadm command with the migrateuser option.
An UPAS incremental synchronization has been run.
I have looked at the properties of the SP user profile.
The UserName property is still valued with : sharept2
I expect the UserName property to be valued with : TestUser2.Sharepoint
Why the UserName property has not been updated ?
What do I need to do to solve my issue ?
Any help will be greatly appreciated
