This is real confusing then...
I read jForum documentation on SSO couple of times...They clearly say [net.jforum.sso.CookieUserSSO] is default for sso.implementation property...Yes it say "You can also implement your own SSO class to support your particular situation" as well and there is an example MyUserSSO for CookieUserSSO...

I am new to jForum and still trying to catch up with lot of things...
