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

auth_master_user_separator=* 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 :

admin:{SHA}gfdokoir9ewerre

Then i authenticate using:

user*admin password of the administration.

Greetings,

My company is currently using dovecot with ldap, I am in the process of migrating this over to Exchange. However, to make the process a lot smoother I need to make use of the master user function of dovecot to enable access to other users mailboxes without needing their password. I've gone through the documentation but it looks like this might not be possible with an ldap backend.

The wiki isnt exactly crystal clear on where the master user config needs to go. I've generated a passdb file with an admin user and password.

Any information that would go to help would be very welcome.

Cheers
