The authentication header received from the server was 'Negotiate,NTLM'. The end user authentication is passed inside the content of the request and is not the problematic part. On the other hand, I found a consideration that a custom Authorization scheme can be unexpected and unsupported by some clients and leads to custom code anyway, so it's better to use a custom header since clients don't have any expectations about it. And no longer do you need to put the username and password in the URL or think of disabling authentication for the whole SOAP adapter. In this case, you need to enable SSL offloading and client certificate authentication on Proxy IIS10 Server with ReverseProxy (on host secure-dev-ms01) only and disable SSL offloading and certificate auth in IIS7. For server authentication, you must have a known-hosts file on the client machine. Some HTTP client software expect to receive an authentication challenge before they will send an authorization header. Instead, OAuth 2. Almost every REST API must have some sort of authentication. This cookie value will then be added to subsequent requests headers sent to other services. Auch unsere Pentest-Komponente.
