'''Video summary:''' A third, more complete CRPF KT session covering the same dual Network Edition / Open Source Zimbra architecture as the other two videos on this page (VuCx41rFxds, IqYu4dBUpNU) -- same 429-domain, rank-based split, single-URL Flask/nginx login router (here specified as active-passive via a shared virtual IP, not active-active) -- but adds several details not covered elsewhere: LDAP uses true MMR (multi-master) replication between the two LDAP nodes so either can go down without impact; "archiving" here isn't Zimbra's built-in archive feature but a simpler BCC-style mechanism -- each user has a paired hidden "username_in"/"username_out" mailbox that silently receives a copy of every inbound/outbound mail; authentication is handled entirely through the client's own Windows Active Directory server rather than Zimbra's native LDAP auth, with a self-service password change/reset page (OTP sent to the user's registered number) integrated against that AD server; and a NextCloud server is deployed separately for document/file management. Confirms overall scale: ~5000 licensed users (Network Edition) plus additional Open Source users, across 429 total domains, as two separate multi-server Zimbra instances.
