Microsoft has announced that the connector "WS-Trust will be terminated as of April 4, 2022. This will cause interruptions to services that use the WS-Trust Authentication Protocol."
But it was not passed on how to create this other connection, it says in some places, but nothing concrete.
In the Email itself came this subject: "What action do I need to take?
To avoid impacting your operations when this disablement is enforced, start transitioning your WS-Trust authentication protocols to an OAuth-based connection string."
