I think you can achieve this using the Credentials Input node. I think that the Use KNIME Server Login option will give access to the windows login when running locally - not 100% certain though - you may need to reenter the windows password in this case.
firstly, thanks for your fast reply.
I have just tried it, but I don’t have a KNIME-Server yet.
I understand your solution and it will work with the server for sure, but for now, I can’t use it this way.
I guess it could be useful to explain it a little more detailled:
I use a MS-SQL-Database which is defined as confidential. The only way, someone is allowed to access to, is via PKI-certificates, so it’s not possible to get access only by WinUser and password. Nevertheless, we need access with KNIME as well. TBH, I am a bit impatient and don’t want to wait for the KNIME-server.
Is there maybe a solution to get the WinAuthentification in another way (perhaps a java snippet )?
