These result codes (called "non-error" result codes) do not indicate an error condition:
success (0),
compareFalse (5),
compareTrue (6),
referral (10), and
saslBindInProgress (14).
The success, compareTrue, and compareFalse result codes indicate successful completion (and, hence, are referred to as "successful" result codes).
The referral and saslBindInProgress result codes indicate the client needs to take additional action to complete the operation.
