When enabled, this option causes Samba (acting as an Active Directory Domain Controller) to stream authentication events across the internal message bus. Scripts built using Samba's python bindings can listen to these events by registering as the service auth_event. This should be considered a developer option (it assists in the Samba testsuite) rather than a facility for external auditing, as message delivery is not guaranteed (a feature that the testsuite works around). Additionally Samba must be compiled with the jansson support for this option to be effective. The authentication events are also logged via the normal logging methods when the is set appropriately. no
