I've got an interesting situation:
I've got a domain e.g. FOOBAR.FI. The Netbios domain is due to historical reasons BARFOO. When I use UPS to import accounts from the FOOBAR.FI domain, the user account names in SharePoint are given the id of FOOBAR\<useraccount>.
This works so and so. Users are identified and My Sites is fine. However the organizational chart and other fields where you can specify another user don't work as they should. If the manager is specified from AD, the organizational chart works.
However, if I edit a profile and check the manager, it's in the form of FOOBAR\<useraccount>. SharePoint highlights this and a tooltip says that the account cannot be found. As a suggestion, it gives BARFOO\<useraccount>, which is found from
the AD. All fine and dandy, until you check the organizational chart, which turns out to be empty at this point. This is because in SharePoint there's no user with the name BARFOO\<useraccount>, but only those FOOBAR\<useraccount> users who've
been imported from the AD.
So bottom line question is: How does UPS select and set the user account name?
