Issue
When installing the server console, we recommend using SQL Server authentication for multiple users.
If, however, Windows Authentication is chosen please observe the steps listed in the Solution below.
Solution
1) Create an AD security group and populate it with your chosen administrator users.
2) Map this security group in SQL studio to the DirSync Pro databases and give the group DB Owner permissions.
3) Add the admin user to the Local BTDirsyncPro group on the server.
