Which type of authentication are you using. I find that SSL-Slient authentication causes getUserPrincipal() (or getRemoteUser()) to return null. I don't know why this is. BASIC or DIGEST authentication should work OK, though.
If you describe your problem to me again, I may have some insights as I am currently working on something similar.
