I have an ldap configuration but i have done the same as you.
In dovecot.conf:

  passdb passwd-file {
    args = /usr/local/etc/passwd.masterusers
    master= yes

I have used this to generate passwd.masterusers file:

htpasswd -b -c -s /usr/local/etc/passwd.masterusers user password

The passwd.masterusers :


Then i authenticate using:

password of the administration.
