The value of tmnxNtpConfigAuthCheck specifies whether or not to skip
the rejection of NTP PDUs that do not match the authentication key or
authentication type requirements. When tmnxNtpConfigAuthCheck has a
value of 'true', authentication PDUs are generated and NTP PDUs are
authenticated upon receipt. Mismatches cause a counter to be
incremented for a type mismatch and a counter for a key value
mismatch.
