Do xdmcp and the standard greeter declare separate PAM service names?
Otherwise it's still not practical to do this by default without introducing
a security hole, because unless the two can be distinguished by "tty" (i.e.,
X display) values, the PAM behavior is going to be either insecure, or block
out this use case.
