Hello,
I am running Zimbra OSE for last 1 year with more than 450 accounts and its been great to work with Zimbra

.
Now I am planning to have a secondary mail server configured with zimbra which can act as a failover of primary. Few of my requirements are
1) All users account password have a 90 days expiry and so when a secondary is configured I would like to have a daily sync for user passwords.
2) All accounts data should be sync'ed every 6 hours (I got a solution to use imapsync. I tested it and it work fine, if any better solution let me know)
So my primary concern is on first problem. I would appreciate any help in this as I need to configure secondary mail server to save any downtime for my email users.
For the first problem I tried steps
Using_LDAP . It didnt function as intended as both servers have different hostname.
Looking forward for your reply....
New Year Wishes
Regards
