If you're just looking for simple authentication then you may want to take
a look at: http://shiro.apache.org/. I've used it for simple authentication
all the way up through using an LDAP backing store and it's pretty simple.
It has some cool things like @RequiresAuthentication annotations that you
can put on any RPC call you want to make sure the user is logged in for.
