Assuming the kadmin client and KDC are running 1.12 or later, you can 
create WELLKNOWN/ANONYMOUS with the -nokey option (instead of -randkey) 
to disable the password fallback.  Or you can "kadmin.local purgekeys 
-all WELLKNOWN/ANONYMOUS" to remove the principal's long-term keys once 
it already exists.  If this is done you should get PKINIT error messages 
from kinit -n if the KDC offered PKINIT and the client couldn't make it 
work, like this:

     $ kinit -n
     kinit: Pre-authentication failed: No pkinit_anchors supplied while 
getting initial credentials

(The PKINIT doc page still says to create WELLKNOWN/ANONYMOUS with 
-randkey, even though it talks about the -nokey option for client 
principals.  I will work on documentation updates based on this thread.)
