hi all,

I've been tasked to add sieve/managesieve to an existing dovecot cluster running 2.1.7 on debian wheezy which is made up of 2 dovecot-proxy hosts as directors and some back end dovecot imap hosts all running the same version.

My problem is that I thought to put the service on the director/proxy hosts since they wouldn't have too much load on it, but when I do I get the following error:

Apr 28 11:00:28 master: Info: Dovecot v2.1.7 starting up (core dumps disabled) Apr 28 11:00:28 config: Warning: service auth { client_limit=50000 } is lower than required under max. load (60000) Apr 28 11:00:34 managesieve-login: Error: proxy: host not given: user=<mailchannel@mydomain.net>, method=PLAIN, rip=192.168.100.207, lip=192.168.100.119, TLS, session=<3/zPY74UOgDAqGTP> Apr 28 11:00:34 managesieve-login: Info: Aborted login (internal failure, 1 succesful auths): user=<mailchannel@mydomain.net>, method=PLAIN, rip=192.168.100.207, lip=192.168.100.119, TLS, session=<3/zPY74UOgDAqGTP>

From searching around, only ever saw 1 result which was to add "executable = managesieve-login director" to the managesieve service, but this made no difference at all and the error is the same.

So I tried to instead use the back end imap servers, but they throw errors expecting the users password to be the common proxy/director password as below: passdb { driver = static args = user=%u password=crypticpasswordagain }

Apr 28 12:03:37 auth: Debug: static(mailchannel@mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): lookup Apr 28 12:03:37 auth: Info: static(mailchannel@mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): Password mismatch Apr 28 12:03:37 auth: Debug: static(mailchannel@mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): PLAIN(85387v92394jks) != 'crypticpasswordagain' Apr 28 12:03:39 auth: Debug: client out: FAIL 1 user=mailchannel@mydomain.net

So with configs below, how is it best to run managesieve that takes the correct login/password without directing to the cluster (or direct if it's easier but must use real user password)?
