Hi, there,

I am playing with the latest 7.0.2 and the single sign on part is not worki=
ng correctly. And I debugged the problem and found the sso member variable =
is always null in AuthenticatorBase class.  Here is the clip of code in thi=
s class I  found it may have a problem. This code tries to find the singles=
ignon valve through all ancestor container, but all the container don't imp=
lement Pipeline interface. And the pipeline is member variable of Container=
Base. I don't know if this is a bug or I didn't configure my server.xml cor=
rectly.  It seems to me sso will never get set if I use standardEngine or s=
tandardHost.

    protected synchronized void startInternal() throws LifecycleException {

        // Look up the SingleSignOn implementation in our request processin=
g
        // path, if there is one
        Container parent =3D context.getParent();
        while ((sso =3D=3D null) && (parent !=3D null)) {
            if (!(parent instanceof Pipeline)) {
                parent =3D parent.getParent();
                continue;
            }
            Valve valves[] =3D ((Pipeline) parent).getValves();
            for (int i =3D 0; i < valves.length; i++) {
                if (valves[i] instanceof SingleSignOn) {
                    sso =3D (SingleSignOn) valves[i];
                    break;
                }
            }
            if (sso =3D=3D null)
                parent =3D parent.getParent();
        }
......

Thanks for looking at this issue.
