Setup

PowerDNS Version Support:

PowerDNS-Admin supports PowerDNS autoritative server versions 3.4.2 and higher.

pdns Service

I assume that you have already installed powerdns service. Make sure that your /etc/pdns/pdns.conf has these contents

PowerDNS 4.0.0 and later

api=yes
api-key=your-powerdns-api-key
webserver=yes

PowerDNS before 4.0.0

experimental-json-interface=yes
experimental-api-key=your-powerdns-api-key
webserver=yes

This will enable API access in PowerDNS so PowerDNS-Admin can intergrate with PowerDNS.

Create Database

We will create a database which used by this web application. Please note that this database is difference from pdns database itself.

You could use any database that SQLAlchemy supports. For example MySQL (you will need to pip install MySQL-python to use MySQL backend):

MariaDB [(none)]> CREATE DATABASE powerdnsadmin;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON powerdnsadmin.* TO powerdnsadmin@'%' IDENTIFIED BY 'your-password';

For testing purpose, you could also use SQLite as backend. This way you do not have to install MySQL-python dependency.

PowerDNS-Admin

In this installation guide, I am using CentOS 7 and run my python stuffs with virtualenv. If you don't have it, lets install it:

$ sudo yum install python-pip
$ sudo pip install virtualenv

In your python web app directory, create a flask directory via virtualenv

$ virtualenv flask

Enable virtualenv and install python 3rd libraries

$ source ./flask/bin/activate
(flask)$ pip install -r requirements.txt

Web application configuration is stored in config.py file. Let's clone it from config_template.py file and then edit it

(flask)$ cp config_template.py config.py 
(flask)$ vim config.py

Create database after having proper configs

(flask)% ./create_db.py

Run the application and enjoy!

(flask)$ ./run.py

SAML Authentication

SAML authentication is supported. In order to use it you have to create your own settings.json and advanced_settings.json based on the templates. Following Assertions are supported and used by this application:

• nameidentifier in form of email address as user login
• email used as user email address
• givenname used as firstname
• surname used as lastname

ADFS claim rules as example

Microsoft Active Directory Federation Services can be used as Identity Provider for SAML login. The Following rules should be configured to send all attribute information to PowerDNS-Admin. The nameidentifier should be something stable from the idp side. All other attributes are update when singing in.

sending the nameidentifier

Name-Identifiers Type is "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier"

c:[Type == "<here goes your source claim>"]
 => issue(Type = "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier", Issuer = c.Issuer, OriginalIssuer = c.OriginalIssuer, Value = c.Value, ValueType = c.ValueType, Properties["http://schemas.xmlsoap.org/ws/2005/05/identity/claimproperties/format"] = "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress");

sending the firstname

Name-Identifiers Type is "givenname"

c:[Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname"]
 => issue(Type = "givenname", Issuer = c.Issuer, OriginalIssuer = c.OriginalIssuer, Value = c.Value, ValueType = c.ValueType, Properties["http://schemas.xmlsoap.org/ws/2005/05/identity/claimproperties/format"] = "urn:oasis:names:tc:SAML:1.1:nameid-format:transient");

sending the lastname

Name-Identifiers Type is "surname"

c:[Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname"]
 => issue(Type = "surname", Issuer = c.Issuer, OriginalIssuer = c.OriginalIssuer, Value = c.Value, ValueType = c.ValueType, Properties["http://schemas.xmlsoap.org/ws/2005/05/identity/claimproperties/format"] = "urn:oasis:names:tc:SAML:1.1:nameid-format:transient");

sending the email

Name-Identifiers Type is "email"

c:[Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress"]
 => issue(Type = "email", Issuer = c.Issuer, OriginalIssuer = c.OriginalIssuer, Value = c.Value, ValueType = c.ValueType, Properties["http://schemas.xmlsoap.org/ws/2005/05/identity/claimproperties/format"] = "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress");
