Accessing an authenticated web service using BizTalk and impersonation

I need to access the SharePoint user profile service.

SharePoint quite nicely exposes:  http://{Server}/_vti_bin/userprofileservice.asmx

It is authenticated, quite rightly so, however the user I am accessing it with has permissions, however it still asks for username and password.

I was getting this error:

The adapter failed to transmit message going to send port "WcfSendPort_UserProfileServiceSoapOneWay" with URL "http://{Server}/_vti_bin/userprofileservice.asmx". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.ServiceModel.FaultException: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Server</faultcode><faultstring>Server was unable to process request. ---&gt; System.ServiceModel.EndpointNotFoundException</faultstring><detail /></soap:Fault></soap:Body></soap:Envelope>

Server was unable to process request. System.ServiceModel.EndpointNotFoundException

Not much help to me…

After some searching I found I needed to use impersonation.

The main reason was from .net I can simply do:
WSService.Credentials = System.Net.CredentialCache.DefaultCredentials;

Now the current user is impersonated and if they have permissions it works. GREAT.

I’m in BizTalk, and I’m on the WCF port…

The port is using wcf-basichttp as the protocol, and it should be able to just I have no idea how.

Well the solution I found is rather simple.

Use a wcf-custom port.  

Setup the basic-httpbinding.

First of all set the transport to client credential type ntlm 


Then flip over to Behavior

It will be blank.  Right click end point behavior: 

Select add extension.

Add client credentials and configure like so:

 After doing this my error went away.
