Hi everybody!
We are planning to replace our MS AD Domain (+ external POP3 mail
server) setup with Samba4 and SOGo.
The challenging part is, that we have two offices at different
locations, each should be able to operate redundantly/independently to
reduce load on the internet. Userdata, Profiles and Mail/Calendar need
to be in sync.
We thought of syncing data/directories via GlusterFS and databases (for
SOGo) via MySQL replication. Dovecot as a mail server can be replicated
using dsync [1].
The clients are Windows XP/7 and will likely use Thunderbird as a
Mail-Client, but we need MS Exchange-Connectivity for 3rd party services
running on some Windows servers.
Most Clients/Users are stationary at one site, but some are moving
between the 2 locations.
Optimally the profiles and mails are synced and the local server is
chosen dynamically (possibly via DNS).
For handling incoming/outgoing mail traffic, the current external mail
server could be used as a relay, but we would love to avoid that.
So basically my questions are:
*) has anybody of you done something like this before and has
encountered problems that can be avoided
*) Can multiple SOGo servers handle the same domain, based on a
Primary/Backup-DC setup of samba4
*) Can SOGo Databases be synced on the fly?
Any help or experience report is appreciated!
Thanks in advance and best regards,
Peter
