Common SiteMinder Deployment Environments

Common SiteMinder Deployment Environments:

  1. Single Policy Store, Multiple Policy Servers and Web Agents
  2. Clustered Environment
  3. Shared User Directory Environment

Single Policy Store, Multiple Policy Servers and Web Agents

This SiteMinder environment contains a single policy store used by 20 to 100 Policy Servers located across the world. For performance reasons, the policy store and user directories are automatically replicated so that each Policy Server communicates with the closest replicated version. Each Policy Server communicates with 50 to 300 Web Agents.Untitled1

 

Clustered Environment

A clustered environment is similar to the SiteMinder environment with a single policy store and multiple Web Agents and Policy Servers. However, in a cluster, the policy stores are copied, not replicated, the difference being that a copied store is a snapshot of the policy store at a specific point in time; it is not dynamically updated. A replicated store is updated automatically. Typically a change is made to a primary database and then the changes are propagated to secondary databases. In addition, you can upgrade one cluster site independently from another and still maintain single sign-on between them.Untitled1

Shared User Directory Environment

In this environment, two sites have multiple Web Agents and multiple Policy Servers, but they maintain their own set of policies stored in two separate policy stores. These sites maintain single sign-on by replicating the same master user directory.Untitled11

Type of Deployment Policy Store Policy Servers Web Agents User Directories Explanation
Single Policy Store, Multiple Policy Servers and Web Agents Single Multiple Multiple Mingle master user directory. Policy store and user directories are automatically replicated.
Clustered Environment Single Multiple Multiple Single master user directory. Policy stores are copied, not replicated,
Shared User Directory Environment Multiple Multiple Multiple Single master user directory. Multiple Web Agents and multiple Policy Servers, but they maintain their own set of policies stored in two separate policy stores. These sites maintain single sign-on by replicating the same master user directory.

    Hi Vibhav, Your article on siteminder deployment is very detailed and informative. I have a question with regards to testing a siteminder implementation. What are the ways we can validate the policies, authentication and how can we simulate a small scale siteminder environment for testing before the production deployment. I really appreciate your response on this regard,
