Unable to Use SASL Authentication
Log file message:
(Active Directory) Not using SASL for authentication, because configuration is incomplete.
Cause
Although SASL Authentication is enabled, the Authentication Realm was expected in the form of a fully-qualified domain name (FQDN), but not explicitly specified.
Resolution
Use the SECURITY_AD_SASL_OPTION_REALM configuration parameter to specify an FQDN.
