SQL connection via Kerberos authentication

Hi!,

Stright to the point: in my TestCase, I need to connect to SQL DB via Kerberos Authentication (and not via JDBC). And I didn't find any way how to do this. 

I also tried to create "new JDBC connection" saved as:

<USER>:<PASSWORD>@DOMAIN.CZ

in File > preferencies > JDBC driver properties

but it ends-up with error:

Failed to init connection for driver [Kerberos], connection string [EXT96004:######@Domain.CZ]

Is it possible somehow please?

And also, can you provide information how to do this in Groovy? (which more important solution for me right now)..

Thanks!
