Hi to all, I'm trying to implement an application on google app engine and I want to be able to manage the identity of my users. I want to use SAML and I found some interesting projects like: http://www.forgerock.com/openam.html. Anyway, now I can't deploy the WAR because the uploader from google fails in compiling some files. Do you know other good choices to manage user's identity? Should I try another way?
