Authenticating to a SQL Server instance as a Windows User via JDBC

Question

I\'m having to support multiple database types for my tenant-enabled web application. Among others, I have successfully supported Microsoft\'s SQL Server, by using the net.s

Answer 1

One of the possible reasons for this error to appear is when you configure you data source to use windows authentication and SQL Server is using Extended Protection mode together with SSL (i'm not sure if SSL is required though). This mode requires the client to send additional information - signed service principal name (SPN) and channel binding token (CBT). See more information about Extended Protection Mode here. Currently both JTDS JDBC and Microsoft JDBC drivers do not support this mode. I couldn't find an official statement from JTDS, but there is an open ticket for Microsoft drivers. In order to configure Extended Protection mode, go to SQL Server Configuration Manager, select properties on SQL Server Network Configuration -> Protocols for %your instance% and change Extended Protection option.
