Master user and non-plaintext auth does not work

Hi, I want to use CRAM-MD5 or DIGEST-MD5 (non-plaintext) authentication for master users, but Dovecot 2.2.13 rejects it with the following log: Sep 1 06:18:08 localhost dovecot: auth: passwd-file(masteruser,10.0.1.20,master,<ZA1s9/oBgAAKAAEU>): Master user logging in as u0001 Sep 1 06:18:08 localhost dovecot: auth: cram-md5(u0001(a)example.jp,10.0.1.20,<ZA1s9/oBgAAKAAEU>): password mismatch Sep 1 06:18:10 localhost dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<u0001(a)example.jp>, method=CRAM-MD5, rip=10.0.1.20, lip=10.0.103.100, secured, session=<ZA1s9/oBgAAKAAEU> PLAIN and LOGIN are OK: Sep 1 06:20:34 localhost dovecot: auth: passwd-file(masteruser,10.0.1.20,master,<SpwmAPsBgwAKAAEU>): Master user logging in as u0001 Sep 1 06:20:34 localhost dovecot: imap-login: Login: user=<u0001(a)example.jp>, method=PLAIN, rip=10.0.1.20, lip=10.0.103.100, mpid=23743, secured, session=<SpwmAPsBgwAKAAEU> Sep 1 06:20:34 localhost dovecot: imap(u0001(a)example.jp): SpwmAPsBgwAKAAEU: Connection closed in=13 out=663 I have the following configuration in my dovecot.conf: auth_mechanisms = plain login cram-md5 digest-md5 disable_plaintext_auth = yes auth_master_user_separator = % passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } # don't work too #passdb { # driver = checkpassword # args = /opt/osstech/etc/dovecot/checkpassword.masterusers # master = yes # pass = yes #} passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } Is this a bug or a restriction of Dovecot? -- -- Name: SATOH Fumiyasu @ OSS Technology Corp.
