Administrators might want to convert their Microsoft SQL Server data source from non-contained to contained, allowing authentication to travel with the database instead of being managed at the server level.
A proper data source backup strategy should be implemented to prevent possible data loss.
- Configure your SQL Server to allow contained databases: 

Should the last command return an error message, use the sp_who2 command to find the SPID of the open connections.
- Create an administrator user for the SQL database: 

- Back in Remote Desktop Manager, in the General tab of your data source, change the type to Microsoft Azure SQL, and set a Username and Password. Click Save. 

- Go to the Advanced tab, click on More settings, and set the Encrypt setting’s value to false. Click Ok to close the window, then Save the modification. 

- Then, tick the Contained database user (recommended) checkbox every time you create a new user for this data source.
