Basic two host replication scenario, SSL failure

[Ivan Lezhnjov Jr.]

This is a follow-up.

I tried synctest and it basically pointed at the same issue.

[root at 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.
