Not really. As a security requirement, if this even really is anyone's 
security requirement, this is pointless -- the ErrCode is set to 0 ("Not 
defined") while the ErrMsg is still set to "Permission denied". The 
server isn't making full use of the protocol at everyone's cost. That's 
why it's a stupid idea, not because of conflicting but equally 
justifiable requirements.
