Hi, 

I have a requirement where I need to send the SAML token I received from AD FS 2.0 to my SharePoint 2013 site via a SOAP request. I've done it as a REST service request and it's working fine. But I need to do the same with a SOAP request. Could some one please point me where is the WSDL for the Claims Authentication services in SharePoint? I mean do SharePoint has a WSDL for _trust endpoint ? 

Regards,

Supun B.

Does any one has an update on this ? Appreciate if someone can help me out here. 

Regards,

Hi Supun,

As my research, SOAP based authentication for SharePoint is only available in form based authentication with URL http(s)://site:port/_vti_bin/authentication.asmx, where the login method is available with parameters username and password. In claim based passive sign in, HTTP redirection is mostly used for post information to SharePoint from STS. Would you please explain the reason about you have to use SOAP method for submitting the token?

Thanks,
