I am trying to use the confluence SOAP service to add users to groups, however when I try to use any method (eg. login method) via the WCF Test client that comes with Visual Studio I get the following errors:

{noformat}
The communication object, System.ServiceModel.ChannelFactory`1[ConfluenceSoapService], cannot be used for communication because it is in the Faulted state.
{noformat}
Confluence Version : 6.1.2
I have the SOAP api enabled through the Confluence configuration.
