Hello, As a step to migrate to a newer version of dovecot, i've been asked to configure a master user for logging in into mailboxes of a dovecot 1.2. I've followed the instructions from this page: http://wiki1.dovecot.org/Authentication/MasterUsers but appearently something is going wrong. I've turned on the auth verbose and what i get in the log is: 2014-06-30 15:25:03 auth(default): Info: passdb(administrator,127.0.0.1,master): Master user logging in as user at domain.tld but the output from a telnet session says: Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=LOGIN AUTH=PLAIN] server ready. a1 login user at domain.tld*administrator <administrator password> a1 NO [AUTHORIZATIONFAILED] Authorization failed what i noticed is that if i type a wrong password i get an AUTHENTICATIONFAILED, which, to me, sounds different from authorization. what am i doing wrong? here is the auth configuration: ____________________________________ auth_master_user_separator=* auth default { mechanisms = login plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb passwd-file { args = /etc/dovecot/passwd.masterusers master = yes pass = yes } userdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb static { args = uid=65000 gid=65000 mail=maildir:/var/utenti/ADS/%Lu/Maildir } passdb pam { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } ____________________________________
