I followed this tutorial
http://wso2.com/library/articles/2010/07/saml2-web-browser-based-sso-wso2-identity-server/
and was able to redirect my application to wso2 login page and authenticate against a LDAP.
Now I want to add one more IDP, e.g. Facebook authentication, and allow users to login either through LDAP or Facebook after it is redirected to wso2 login page.
Is it possible, and if so can you refer me to any documentation on this?
