Already did this -- suggested by Love. The clients address shows
up in all tickets -- both before and after a failed login. As I
wrote I do believe I've done my homework; DNS works, no strange
networking (two machines on the same switch, and in the same broadcast
domain are both KDC and resolv server...) 

One idea though: I do have IPv6 enabled (as in v6-aware stacks and
autoconfig enabled, but no other infrastructure support) on both
hosts. Could it be that this interferes even though all on-the-wire
communication is done over v4 (sniffed and checked, yup), perhaps
as in garbled responses to gethostbyname() or similar?

...still baffled..
