We need to integrate openID into our application, and I was going to try using picketlink for this; I have two questions though. Is openID still supported by picketlink? Also, I tried to download the provider and consumer for openid, and I get the error "You don't have permission to access /maven2/org/picketlink/openid-provider/1.0.3.SP1/openid-provider-1.0.3.SP1.war on this server." when I try to download the provider. The consumer downloaded just fine though.

Mainly you will be using a single authenticator to configure facebook, google (uses openid) etc.
