We are having a problem in which the "Name" portion of some people's profiles are being updated on the periodic sync wiping out the proper displayName which should just be their first and last names and instead replacing it with their account name which is 'domain\username'. I did a full sync yesterday, and just about all the names came in correctly. There was just one that didn't. A double check of active directory showed that the 'Display Name' field was properly filled for all users. A check this morning of the profiles showed that 36 of the over 400 profiles we have now show the improper display name. In active directory, though, the display name field is still fill in properly. What could cause sharepoint to improperly load this field?
