An attempt was made to set a read-only credential.
When the client does WS-Trust exchange with the Security Token Service to obtain the issued token, it sometimes must exchange key entropy with the Security Token Service to arrive at a shared symmetric key. The Security Token Service typically specifies the entropy exchange mechanism to use in its binding. If no such mechanism is specified in the Security Token Service's binding, the DefaultKeyEntropyMode value is used to exchange entropy with the Security Token Service.
