Login to ManagementServer/ServerCommandService.svc returned HTTP 400

Hi,

I am trying to log in to the system using the ManagementServer/ServerCommandService.svc endpoint. It works when I log in as a basic user, but it does not work when I log in as an AD user.

My integration is done in Java, and I use HTTPS for the basic user and HTTP for the AD user.

I receive an HTTP 400 response with no response body. Are there any logs on the Milestone server that I can check to determine the cause of the error?

Thanks.
