Assign SQL Server Login Permissions for AD users

On the MS SQL server, check if the Citavi users have permission to log in to the server. Open the Microsoft SQL Server Management Studio. Then, click Security > Logins.

• If you're using MS SQL Server Express, please make sure that an entry for the group BUILTIN\Users is present. This group should be added by default during the installation (see Microsoft's documentation).
• In other MS SQL Server editions, the administrator must define an AD group that contains all users who will be working with Citavi for DBServer.

The group needs to have the public server role.

Without a group entry, an AD user will be unable to log on to the SQL Server. All additional permissions are controlled by settings at the database level.
