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
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
was unable to process request. —&gt;
Server was unable to process request. System.ServiceModel.EndpointNotFoundException
Not much help to me
After some searching I found I needed to use impersonation.

WSService.Credentials = System.Net.CredentialCache.DefaultCredentials;

permissions it works. GREAT.

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
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.
