What is the Portnox Active Directory Broker (AD Broker)?

In this topic, you will learn what is the Portnox™ Active Directory Broker (AD Broker) software and how it works.

Portnox Active Directory Broker (AD Broker) is a lightweight software agent for installation on user devices. AD Broker is not necessary to use Portnox Cloud but it is necessary for the following purposes:

Installation requirements

AD Broker is only available for Microsoft Windows. If you need to use AD Broker functionality on other platforms, you need a virtual machine with Windows to install and run the broker.

The following are the minimum requirements for installing AD Broker on a Windows machine:

CPU: minimum: 1.4 GHz (x64 processor)
RAM: minimum: 8 GB, recommended: 16 GB
Free disk space: minimum: 1 GB
Connection to the internet on ports 443 and 8081
Connection to the corporate Active Directory or OpenLDAP
For AD integration: domain-joined (member of the Active Directory domain)

Troubleshooting the installation

Multiple AD Broker instances

You can install any number of AD Broker instances on any number of machines. If there is more than one AD Broker configured for your domain, and there is an authentication request for that domain, Portnox Cloud sends that request to all AD Brokers that you configured for that domain. The first AD Broker that responds is the one that is used for this specific request.
