I´ve been testing Zimbra Live Sync as per instructions found here: Server Live sync - Zimbra :: Wiki
After a few tests i must say i´m quite impressed. The sync was seamless. Everything was in there: mails, accounts...
But i´m having a little issue running "live_syncd" on the "ex-live" server. Let me explain.
We have "live server" and "backup server". We run live_syncd on the BACKUP SERVER and it starts syncing with the LIVE server via ssh (after creating keys).
When LIVE SERVER fails, the procedure is simply to stop live_syncd at the BACKUP server and start zimbra there. That is working just fine. live and backup are now reversed.
Now i want to fallback to my ex-live server. The procedure is to start live_syncd on the ex-live, let it catch up with the changes and start zimbra on it, but running live_syncd on ex-live is throwing an error:
"Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)."
And i cannot fallback to the original server. I know it´s related to ssh keys but i can´t find the reason why. /opt/zimbra/.ssh/ is identical at both servers.
