This is a follow-up. I tried synctest and it basically pointed at the same issue. [root@imapsite-replica scripts]# synctest -a cyrusadmin -u cyrusadmin -t "" master S: * SASL PLAIN S: * STARTTLS S: * COMPRESS DEFLATE S: * OK imapsite-master Cyrus sync server v2.4.10-Kolab-2.4.10-1 C: STARTTLS S: OK Begin TLS negotiation now verify error:num=18:self signed certificate I can login if I omit -t "". So, I tried to disable TLS by commenting out tls_* lines in imapd.conf of both hosts and starting the cyrus-imap to serve only imap service (disalbed imaps, pop, etc.) Now, with this TLS-less configuration B switched to master outputs to logs: Jul 11 12:51:09 imapsite-replica sync_client[1444]: couldn't authenticate to backend server: no mechanism available Jul 11 12:52:39 imapsite-replica last message repeated 2 times and A switched to replica outputs the following: Jul 11 12:51:09 imapsite-master syncserver[18209]: accepted connection Jul 11 12:51:09 imapsite-master syncserver[18209]: cmdloop(): startup Jul 11 12:51:39 imapsite-master syncserver[18209]: accepted connection Jul 11 12:51:39 imapsite-master syncserver[18209]: cmdloop(): startup Jul 11 12:52:39 imapsite-master syncserver[18209]: accepted connection Jul 11 12:52:39 imapsite-master syncserver[18209]: cmdloop(): startup Replication doesn't succeed, obviously. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
