As Pid surmised, it's not Tomcat that is giving you different answers. Here's
Tomcat's implementation of HttpServletRequest.getRemoteUser():
public String getRemoteUser() {
if (userPrincipal != null) {
return (userPrincipal.getName());
} else {
return (null);
}
}
[Aside: Don't know why people think return statements need parentheses; maybe
they get paid for programming based on the number of characters used.]
