We’ve identified that the user profile import in the SharePoint 2010 public beta can’t handle hyphens in domain names. The import will succeed but the portion of the domain name preceding the hyphen will get trimmed. When a user logs on a new profile is created but it is orphaned from the imported data. In principal we’ve been able to work around this by migrating the user profiles with STSADM (thanks to my colleague Martin Hatch for the suggestion) but we haven’t put this approach to the test over a sufficient period of time to be able to recommend it firmly yet.
