MSSQL 2008r2 database connection in Pro with windows securit

Hi!

I'd like to ask a question regarding connecting to a MSSQL 2008r2 database with SoapUI Pro. (I couldn't find a subject on this forum regarding this topic, so I'm opening a new one). I've tried this by using the following driver/connection information:
MSSQL(2008r2)/com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc:sqlserver://<HOST:*hostname*>:<PORT:1433>;databaseName=<DB:*dbname*>;user=<USER>;password=<PASSWORD>;

When I now try to connect to the database in a Datasource step in a testcase, it doesn't seem to be able to connect. I've tried to connect by using a Groovy script (in SoapUI free version) and it took me a while, but I got it working by using the jtds driver (

Sql.newInstance("jdbc:jtds:sqlserver://HOST/DATABASE;domain=DOMAIN", "USER", "PASSWORD", "net.sourceforge.jtds.jdbc.Driver")

).

Obviously, I hoped Pro would solve this problem by using a project overall JDBS-connection, but as mentioned above, this won't work. I also tried installing the jtds drivers and using the jtds connection string in the JDBC connections setup, but this won't work either.

Any suggestions? Could windows security/authentication on the SQL Server have anything to do with this?

Thanks!

Regards,
Jeroen.
