Hi,

I’m creating two rails applications lets call them appA and appB. They  
will  
each be running on a subdomin like [appA.domin.com](http://appA.domin.com).

I need a way to share the User table so the login/passwords will work of  
both. I’d also like to keep the app DRY and not have to  
repeat the Account Controller in each app. My first thought was to  
create a  
3rd application and subdomin for account stuff only. So it would be  
[account.domin.com](http://account.domin.com) and each application would use its User table.

What do you think? Has anyone had the same problem?

Thanks,  
Jonathan Spooner
