Likely the difference is that Dovecot keeps the LDAP connection open for a very long time, while MTA likely recreates new connections often (maybe even every time). I guess the fix would be to simply treat that error as "reconnection required": http://hg.dovecot.org/dovecot-2.2/rev/ea38559ffd4e
[Dovecot] auth failures
Hello, last week and today our dovecot pop3 server stopped responding. Without any other logentries dovecot start to log only this: Dec 12 09:14:12 mbox1 dovecot: auth: Error: ldap(testuser,192.0.2.110,): ldap_search(base=ou=accounts,dc=example,dc=de filter=(&(|(uid=testuser)(mail=testuser))(!(state=blocked failed: Operations error For every pop3 Session, ~2000 per Minute ..., over 10 Minutes I send dovecot a SIGTERM. After dovecot was started again, all was fine again. # doveconf -n http://postmaster.datev.de/tmp/dovecot.conf The LDAP-Server itself did resond to queries in the same timeframe. I know this because the MTA on the same host was able to deliver messages into mailboxes. Any hints?
