I am consuming services through Soapclient with a Kerberos authentication.
A website is hosted in Server A and accessed through Kerberos authentication and web services is hosted in Server B and again accessed through Kerberos authentication.
Web service responds with different personal content based on the authenticated user. And same Active Directory is used for both Server A and Server B Authentication.
The server A consumes service from Server B and post-process the response before rendering it to the browser. The user browser has access to all the contents in server A and we do have access to the WSDL on server B.
The problem is with SoapClient as it is not successfully transferring User Kerberos authentication to Server B Service.
We have the following error message:
SOAP-ERROR: WSDL analysis: impossible to load from 'https: //***********/index.php? Wsdl ': Can not load an external entity "https: // **** ******* / index.php? Wsdl"
When Kerberos authentication is temporarily disabled then the Service can be accessed via SoapClient.
Server A is under IIS with PHP 7 installed.
To Impersonate User, we set up Kerberos Double Hop for the website.
Is it possible to transfer Kerberos authentication information with SoapClient?
