auth_debug=yes would help debugging this. Seems to work correctly with me: dovecot: Nov 30 04:40:56 Info: auth(default): cache(test,127.0.0.1): hit: dovecot: Nov 30 04:40:56 Info: auth(default): cache(test,127.0.0.1): User unknown .. dovecot: Nov 30 04:41:11 Info: auth(default): cache(test,127.0.0.1): expired dovecot: Nov 30 04:41:11 Info: auth-worker(default): sql(test,127.0.0.1): query: select password from users where username = 'test'
