I have a application which is of web type. But here is the catch. You login to your windows machine with your username / password. Once the Application opens up it automatically logs in with the Windows Username and Password. Its how the way it is designed.
Now, I added Authorization Manager and gave all of it, it still says 401 error Invalid username and password.
It is a NTLM Authentication.
The HTTP Authorization Manager needs to be populated as follows: Username: must match “User logon name” for Windows Domain Password: Windows Domain Password Domain: should be “what you see in Windows Security pop-up” as this is what real browsers do. If you are uncertain you can type a fully qualified domain name into that field you can just use “domain” or “domain.local”. Other fields like “Base URL” and “Mechanism” can be left as is.
