Hate to follow up my own post, but the above strncpy resolves
to 
      strncpy (utx.ut_id, utmp_id, 0)

And the quite a bit more is being copied than anticipated.  The
modification I made is:

     strncpy(utx.ut_id, utmp_id, sizeof(utmp_id));

And I can now login in successfully.

Now back to my original question of why it gets the login error about
not being able to contact any KDC :-)
