400 Bad Request during SOAP login

I am attempting to make protocol integration from non-Windows (Ubuntu) environment. Given that we must login via a valid basic user which in turn requires SSL/TLS, find the HTTP request below:

POST /ManagementServer/ServerCommandService.svc HTTP/1.1

Any idea why I am getting the 400 bad request?

I am very sorry for my very late reply. We must have overlooked this question.
