With Microsoft SQL Server, you can either let the database server or a Windows domain server handle the authentication. The database server handles it by default using the database user and password you enter for the connection.
To let a Windows domain server handle the authentication instead, you must use the SQL Server (jTDS) JDBC driver (bundled with DbVisualizer).
If you run DbVisualizer on a Windows OS client in the same domain as the SQL Server database, leave the Database Userid and Database Password fields in the Connection tab empty. This is also known as Single-Sign On (SSO).
Note: SSO only works if you installed DbVisualizer using a Setup installer, not if you used an installation archive, because the installer also installs the DLL files needed for SSO.
If you run DbVisualizer on another OS in a network with a Windows domain server, enter the Authentication Domain name in the Options area in the Connection tab. You must also enter the domain user and and password in the Database Userid and Database Password fields. The driver then authenticates with the domain server and then uses those credentials to log in to the database server.
