For some reason Dovecot seems to be throwing login errors since earlier today, with no changes on the server.
Jul 24 01:22:12 web6 dovecot[2830]: auth: Error: apnscp(user@domain.tld,,<qCCK+qA6zrYC5cla>): user not found from userdb
Jul 24 01:22:12 web6 dovecot[2830]: imap(36601): Error: auth-master: login: request [1485701121]: Login auth request failed: Authenticated user not found from userdb, auth lookup id=1485701121 (auth connected 1 msecs ago, request took 1 msecs, client-pid=36600 client-id=1)
Jul 24 01:22:12 web6 dovecot[2830]: imap-login: Disconnected: Internal login failure (pid=36600 id=1): user=<user@domain.tld>, method=PLAIN, rip=, lip=, mpid=36601, session=<qCCK+qA6zrYC5cla>
Any idea on what’s wrong with it?
