I have a problem with SharePoint. Basically the SID of my Windows Account changed (not sure why, still investigating) and SharePoint simply doesn't know me anymore - I get access denied messages and the like.
Is there a supported way to change the SID on a SharePoint user? On a Test setup I successfully changed the tp_SystemID in the UserInfo tables, but that seems too much of a hack for now.
As changing my SID in Active Directory is not possible, I'm not really sure how to proceed from here.
