My test results with current code don't match this claim.  I do see a
bug that the kpasswd_server -> admin_server fallback doesn't work for
kinit password changes, but the presence or absence of master_kdc
doesn't seem to have any relevance.  (Nor would one expect it to, since
password changes don't go through a KDC.)
