We have a SharePoint 2010 server. Since the start, we only had 1 domain. Now, company has decided to move some users on another domain. These users will not actually be moved, they will be created as a new user in the new domain and their previous domain ID will remain active for an year or so.
When doing so, SharePoint is treating the user in both domains as different. I want to preserve history, permissions, etc. associated to the user irrespective of the fact whether he logs in from previous domain or the new domain id.
