We write that config entry if the encrypted padata response from the KDC
contains a padata element of type 136 (PA-FX-FAST).

When I kinit against an old MIT KDC, or against the AD 2003 KDC we have
here, the code does not see such a padata element and does not write the
config entry.  Without further investigation on your end, I cannot
explain why you are seeing the config entry in your tests.
