Hi all,

For our next project we are required to integrate a rails application  
with a  
PHP application.  
The PHP application is going to be used to authenticate users. When the  
user  
is logged into the PHP application, the user should automatically be  
logged  
into the Rails application (Single Sign On).

What might be a good strategy to achieve this result? Maybe somebody did  
something like this before?

Regards,

Harm

Cookies are the easiest way I have found. With a little effort you  
could use sessions… PHP sessions are plain text but ActiveRecord  
sessions are serialized by default.

Hi Greg. I was quickly browsing your site and came across your  
database schema

I was wondering what program you used to create it 🙂

Thanks
