[Dovecot] Master Password not working

Trying to get the master password to work. What am I doing wrong? Trying this test:

/etc/dovecot.masterusers master:{plain}test

auth_master_user_separator=*

auth default_with_listener { mechanisms = plain

passdb passwd-file { # Master users that can log in as anyone args = /etc/dovecot.masterusers master = yes #pass =yes }

passdb passwd-file { # Path for passwd-file args = /etc/vmail/shadow.%d }

userdb passwd-file { # Path for passwd-file args = /etc/vmail/passwd.%d }

socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } }

}

telnet localhost imap Trying 127.0.0.1... Connected to localhost.ctyme.com (127.0.0.1). Escape character is '^]'.

• OK Dovecot ready. 1 login master*marc@perkel.com test 1 NO Authentication failed.

Thanks in advance.
