MyID Authentication Server High Availability Guide

This guide outlines the implementation of high availability, load balancing, and redundancy for MyID Multi-factor Authentication (MFA) systems. It describes the deployment of MyID Authentication Servers within enterprise environments, recommending at least two servers to ensure reliability. The document details the integration of MyID with Active Directory, explaining how user information is replicated across multiple Domain Controllers without schema extensions. It presents the architecture of MyID, including various agents such as the MyID Windows Desktop Agent, MyID Exchange Agent, MyID ADFS Agent, and MyID RADIUS Server, all designed for automatic high availability. The guide further elaborates on two deployment methods: Active-Passive and Active-Active, explaining how each method ensures that authentication requests are processed efficiently and reliably. Additionally, it discusses the services provided by MyID Authentication Servers and the necessity of load balancers for maintaining service availability.
