Hi,
I've just setup a testing enviroment for director, and it's not working
as expected. I have just 1 director (called director) and 2 dovecot
servers (dovecot1 and dovecot2); these are exact copies.
First problem: when both dovecot servers are up, every imap connection
is redirected to the same server as you can see here:
$ sudo doveadm director map
user mail server ip expire time
<unknown> 158.227.4.186 2012-06-06
13:34:12
<unknown> 158.227.4.186 2012-06-06
13:34:27
<unknown> 158.227.4.186 2012-06-06
13:34:34
(I don't know if that <unknown> is good or not)
I've tried with 3 different users and ips to no change, users are always
directed to the same host.
Second problem: if I try to add/remove/modify one of the dovecot
servers, the output of doveadm director map/status seems to be ok, but
any new user connection fails with this log:
Jun 6 14:51:59 director dovecot: director: Warning: Delaying new user
requests until ring is synced
Jun 6 14:52:27 director dovecot: director: Error: director: User test1
host lookup failed: Timeout - queued for 30 secs (Ring not synced for 73
secs)
Jun 6 14:52:31 director dovecot: imap-login: Aborted login (auth
failed, 1 attempts in 34 secs): user=<>, method=PLAIN,
rip=158.227.4.186, lip=158.227.4.185, TLS, session=<Oyx9O83B/wCe4wS6>
Any clue?
This is the dovecot config -n output:
# 2.1.7: /usr/local/etc/dovecot/dovecot.conf
