Configuring Plesk multi DNS server is a breeze accept for setting the Bind permissions.
Configuring Virtualmin Slave DNS servers is also fairly easy if you’ve done it a few times.
A confusing situation arises when you use the same slave server for both products.
The reason why this is a mission is because of the confusion array of configuration files and where to put what, especially the keys used for Plesk. Also you don’t want to break a working Virtualmin configuration.
The three primary configuration files that you will be working on are:
- cat /etc/bind/rndc.conf.options
- cat /etc/bind/rndc.key
- cat /etc/bind/named.conf.options
To get yourself oriented, login to the Plesk Slave server configuration screen and look at the new slave server configuration landing page:
Changes

Allow new zones
Add allow-new-zones yes; to /etc/bind/named.conf.options. Add it to the bottom with a comment.

Copy algorithm and secret
The algorithm suggested is hmac-md5. Your Virtualmin slave server might already be using hmac-sha256. Be sure to use hmac-md5. This you will find in rndc.key. Do not copy as per slave wizard on Ubuntu. You can uncomment the old algorithm and secret.
Warning: You don’t have to specify a new key name!

The final step is to update named.conf, and not named.conf.options!
Add the sections as per the slave config.
