Actually I am interested in Java AA framework that supports many types of A&A. I found that exist JAAS, but don't fond any information about OpenId support. Maybe there exists a module to use it? Spring security supports OpenId but I just want to see any alternative. Also I read that Spring Security is a little bit complicated.
I think it mostly common functionality and there must exist the way to simplify developer life and do not force him to reinvent the wheel.
