Unable to connect to MSSQL server using windows authentication



When using Pega 7 installed on Websphere (WAS) and MSSQL Server a database connection using Windows authentication fails to connect. The connection to the same database is successful when a direct user ID and password are used.

Error Messages

Test connectivity fails. "connection couldn't be established."

Steps to Reproduce

Create a data source in WAS using Windows authentication.

Root Cause

This is caused by a limitation of the MS SQL JDBC driver. Unix systems using the JDBC driver cannot connect to a system using Windows authentication. As such, if WAS is being hosted on a unix system, Windows Authentication is not a supported option for connecting WAS to the database.


Another method of authentication must be used as Windows authentication is not supported under the described scenario.
