That is the expected behavior given what you have done, yes.  Clients that 
obtain fresh tokens will not be able to authenticate to the AFS servers.

You need to take the keytab you obtained from the above "ktadd without 
-norandkey" and use asetkey to add that key to the appropriate KeyFile (if 
it's a 1DES key), or ktutil to add it to the rxkad.keytab (otherwise).
