Workflow Manager 1.0 – Authentication Failed

Posted: May 5, 2013 in Development

Today getting started to play a bit with Workflow Manager ran into an issue attempting to use  WorkflowManagementClient to connect to the service.

The error was

Authentication Failed. Valid credentials must be provided for one of the following protocols: Negotiate. HTTP headers received from the server

In my case, to fix this issue, installing Windows Authentication feature worked for me


Hope this helps
