How to do it...

The procedure to deploy an external SSO has two stages. The first stage is similar to deploying a VCSA and most of the critical configuration is done in stage 2.  We will also cover the steps required to join a PSC to an existing SSO domain for high availability and multi-site configuration. The steps will be covered in two separate parts, part-1 will cover the deployment of a new PSC for a new SSO domain and part-2 will cover joining a PSC to an existing SSO domain.
