issues connecting to ms sql server with integratedsecurity = true

The new 4.1 Microsoft SQL Server connector fails to connect to DB on the local system. I have added the following JDBC Parameters:

integratedsecurity = true

instancename = “Name of SQL Server instance”

in the Connection Settings I have entered:

Hostname: “Name of my Computer”

Database name: “Name of DB”

Authentication: None

All other settings are unchanged.

The SQL Browser service is active.

The

sqljdbc_auth.dll

is copied to Windows\System32

Using the general DB Connector works like a charm.

What I’m doing wrong?

Any hints are welcome.

Regards,

Karl
