[Pkg-pdns-maintainers] Bug#793188: pdns-backend-mysql: Generated pdns.local.gmysql.conf is missing port variable

[Koen C.]

Package: pdns-backend-mysql
Version: 3.4.1-4+deb8u2
Severity: important

Dear Maintainer,

* Installing pdns-backend-mysql with dbconfig-common 
* What did I do: Passwords for administrative user and powerdns user are given during setup, installation with 'apt-get install pdns-backend-mysql pdns-server'
* Actual outcome: Configuration fails with messages:
