PHP - SOAP Connect with Auth/NTLM (between Linux to Win) & Microsoft Dynamics NAV-SOAP Webservices

Here are the system field description: The Webserver where php is running has following setup: Server OS: Linux Debian PHP: 7.1.26 Apache/2.4.25 The SOAP-Modules are enabled. Curl is enabled, too. The Webservices to connect with php are running with: Server OS: Microsoft Server 2019 Microsoft Dynamics NAV 2009 Webservices Technology: SOAP-Webservices The Webservices are tested with a local browser e.g. chrome. the authentication and soap-requests and soap-responses are working with the browser login credentials. I tested them with the browser plugin "boomerang". The challange: create a simple php-script with a working authentication (basic authentication or ntlm authentication - both method are supported as far as i know). maybe there are some setting which has do be done at the microsoft dynamics nav webservices. then create a simple test-request (with soap), parse and print the response in a webpage. an example requested is attached. (soap is having a easier way then writing the complete xml-code - just used it for testing with boomerang)
