Has anyone gotten this Ateam Example (Collecting additional credentials) working?

Hi,

I am trying to get a scenario that is similar to the Ateam's "collecting additional credentials" example (http://www.ateam-oracle.com/oam-11g-custom-authentication-plugins-collecting-additional-credentials/ ) working, but am having no success at all, so far.

I think that I understand what they are suggesting conceptually, i.e., they have a custom authentication module that is designed to be processed twice:

- The first time, it finds a request parameter ("OTPin") as empty, so it sets the processing up to serve a custom login form (the 'additional credentials') and

- The second time, it finds the "OTPin" request parameter populated, and then processes it.
