Progress on UserSourceProfile Demo?

Last September, a request was made for an example project for a UserSource, here:

I’m wondering if there is any progress on an example within IA, or if anyone else has a basic example they care to share. Assuming IA owns the IP, the InternalUserSource code would probably do the trick.

I am tasked with integrating an RSA SecurID login with Ignition. I am finding the API to be pretty slim in this area.

Barring a full-blown example, an idea of what a basic implementation of the getRoles() and getUsers() function in AbstractUserSourceProfile would look like would be fantastic.
