A user has two AD accounts, a 'user' account and a 'domain admin' account. He is in a SharePoint group that has contribute access to the sub-site. There's a document library in the sub-site which inherits permissions. When the user tries to access with his domain admin account, he gets an access denied error, the domain user can edit documents. Any pointers appreciated!
Double the way you give permission in your site collection. When you say he is in a SharePoint Group , how you grant the permission? Do you add the domain user directly to the SharePoint Member Group or do you add a AD group to the SharePoint Member Group. If his domain admin account does not have access , can you add his domain admin account to the SharePoint Member Group?
