Admin entered an existing consumer key and secret to use for friending but the OSLC Remote Application refused to authenticate the request.
The OSLC Remote Application rejected this consumer.
You should try the following steps:
confirm the consumer key is approved, then double check the consumer key and secret and try again
if it still fails
report the error to the admin of the OSLC Remote Application. This admin should create a consumer key that can then be used in OSLC Connect when registering a friend.
