How to implement multiple custom realms with RPX?

Question

Right now I have a free RPX account for integrating Open ID into my web site. I understand that to get a custom realm with RPX (e.g. signon.example.com versus example.rpxnow.com) I need to sign up for the premium service level.

Before I can make a decision, I need to know some details on how custom realms are managed with RPX. I have a couple specific questions which I haven't been able to find answers to in the RPX docs:

How to implement multi-tenant scenario?

I have a multi-tenant web site, where each customer has a custom URL rooted off the main URL, e.g.:

• http://bob.example.com
• http://alice.example.com
• ... etc.

Each customer will be allowed to have their own set of Open ID users. In RPX will I be able to have a realm for each customer URL? I'm hoping there's a way to have a wildcard realm to cover all customers using the above URL scheme.

How to provision custom realms?

What is the actual procedure to go about provisioning each custom realm URL to use with RPX? Do I need update my DNS records for each customer URL to point to the RPX servers?

Answer 1

The custom realm for RPX can be configured to use a single subdomain (signin.example.com) that then can call back to the individual websites, or you can configure a wildcard realm (*.example.com) and have the same RPX application work for all trust roots. There are small pros & cons to each.

To turnup a custom realm you have to add a dns CNAME to point a name on the RPX side. JanRain will handle the rest of the process, and when it is turned up you will have access to the dashboard & api key just like the free version you are using (but with more features ;))
