We are using symfony2 as our framework to built the application which has different firewalls like admin, client and customer.
Now I want to built SSO using SAML(CAS) or OPENID in symfony2. Which will communicate with my application and provide the authentication and with other applications also through web service.
Please suggest some bundles which are already built for SSO and which is better SAML or OPENID.
Thank you in Advance.
