anybody knows useful rubygems/rails plugins for implementing
Single Sign on?
no need to use gem or plug-in just write your custom code
add on attribute user_login : boolean to user table
when ever user logins set user_login as true and after session out or logout set user_login as false
every time user login check the user_login value if false then allow him to login,
otherwise tell One user already login.
Have a look this post:
I have discussed SSO with devise and omniauth.
Hope this helps.
Er… That’s not what SSO means.
@OP: OmniAuth by Intridea is quite famous, and a lot of people use it.
Here’s a guide I found helpful for SSO using omniauth + devise
Thank you all!
