That's on the client machine? Does "scanimage --help" on the server
work?

My first guess is that this is not really a authetication request but
some sort of data destruction somewhere. One hint is the segfault.

Does the same happen with "scanimage -d hp --help"?

On both server and client?

To find out more about the problem, could you please send us the output
of

SANE_DEBUG_SANEI_WIRE=255 SANE_DEBUG_NET=255 scanimage --help

It may be worth a try to run saned on the server in debug mode:
Disable it in inetd (or xinetd) and start it like this:

SANE_DEBUG_HP=255 saned -d255

Please send the output when scanimage --help is called.

Bye,
  Henning
