Integrating PHP app with Ruby on Rails app?

[ryan.cheng]

Hi Ruby(and Ruby on Rails) Gurus,

I am working on a website that uses Drupal as the CMS and ruby on rails
as the main app. I would like to integrate the two in a way so that the
user does not have to login twice, once for Drupal and once for the
ruby on rails app. Does anyone have any experience with this? I was
thinking of have my ruby on rails app read the authentication cookie of
drupal. However, I am not sure how to decode the drupal cookie or if
this would work. While searching for a solution and I encountered this
article but I am quite confused by it.

Does anyone have an idea?

Thanks in advance.

Sincerely,
Ryan Cheng
