dovecot - Sep 2014 - Configure Dovecot Master User

Hi,

Does anyone have any idea or hint how to configure dovecot master user?
I'm already on it for almost fifteen days and can not find a solution.
I appreciate any help,

Clovis

Hi Clovis,

try something like this:

**In this example you should have your users in a MySQL database.

On /etc/dovecot/conf.d/10-auth.conf file add this:

  # Master login <username>*master-user
  auth_master_user_separator = *
  # Use for master login
  passdb {
    args = /etc/dovecot/dovecot-sql-master.conf.ext
    driver = sql
    master = yes
    pass = yes
  }

Create /etc/dovecot/dovecot-sql-master.conf.ext file with this content:

  driver = mysql
  connect = host=<mysqlserverhostname.com> dbname=<database name> 
user=<user> password=<pass>
  default_pass_scheme = MD5-CRYPT
  password_query = \
    SELECT Password AS password \
    FROM   Users \
    WHERE  User = 'master-user'

  user_query = \
    SELECT Password AS password \
    FROM   Users \
    WHERE  User = 'master-user'

To do tests:
  telnet your-dovecot-server.com 143
  AUTH LOGIN <user>*master-user <master-user password>

Good Luck

It's quite simple:

# Authentication for master users. Included from 10-auth.conf.

# By adding master=yes setting inside a passdb you make the passdb a 
list
# of "master users", who can log in as anyone else.
# <doc/wiki/Authentication.MasterUsers.txt>

# Example master user passdb using passwd-file. You can use any passdb 
though.
passdb {
   driver = passwd-file
   master = yes
   args = /etc/dovecot/passwd.masterusers

   # Unless you're using PAM, you probably still want the destination 
user to
   # be looked up from passdb that it really exists. pass=yes does that.
   pass = yes
}

then use htpasswd from Apache to generate the file 
"/etc/dovecot/passwd.masterusers"

The documentation explains it quite well:
