Certificates seems to be fine. A synctest from the master to the replica
(= server) looks like this:

synctest -a syncadmin -u syncamdin -t '' server

Restarting Cyrus on the master comes up with this login without TLS on
the replica:

-----------
Feb 19 02:24:55 tripp cyrus/syncserver[22549]: accepted connection
Feb 19 02:24:55 tripp cyrus/syncserver[22549]: cmdloop(): startup
Feb 19 02:24:55 tripp cyrus/syncserver[22549]: login: server [xxx]
syncadmin DIGEST-MD5 User logged in
-----------

Ciao!
