Userservice wont accept connections


Has anyone managed to get the userservice working properly ? I keep getting the following error:

2008.08.04 11:35:33 An unauthorised user service request was received: type=add

Looking at the source this appears to be a mismatched secret, but I confirmed the secret is correct in my url

curl http://devserver1:9090/plugins/userService/userservice?type=add&secret=mysecret& username=kafka&password=drowssap&name=franz&

Any ideas ?
