I have the opposite problem from Randall https://community.esri.com/message/540389#comment-540389
I used Add User tool' in ArcCatalog to add a user, but the user has not been able to create a new feature class or edit. I used ArcCatalog >Manage> Privileges to also add all I can for this user to the particular feature data set he is working in, but apparently it is not enough. I'm using Arc 10.3.1, SQL Server 2012, Windows Server 2012, and OS authentication.
Is there a way with OS authentication that I can make a database connection with the users credentials so I can test how the database is working for him?
