I tried to log in as test@some_domain. From thunderbird client. Although, I get this logged after before mentioned log:
imap-login: Disconnected (auth failed, 2 attempts in 14 secs): user=<test>, method=PLAIN, rip=some.ip.addr.here, lip=another.ip.addr.here, TLS, session=<rQT+ziijGE1tpoAB>

Did you try to log in as user "test" or "test@some_domain" ?
Is seems to me that you did not use full username (Error:
passwd-file(test,).
( %d domain domain part in user@domain, empty if user with no domain )
