Does the ES4000 support Active Directory?
Yes. The ES4000 automatically detects common Active Directory (AD) settings and configurations, enabling policy enforcement and authentication by user. The ES4000 synchronizes with Active Directory to ensure that email continues to flow if the AD server fails, and notifies the administrator of a failure via email and on the system status page of the management console. Active Directory is currently the only authentication protocol supported. Administrators can import user lists from other systems or enter them manually. SMTP recipient validation is used in the absense of LDAP authentication.
