I now realize what the answer is: my firewall. I needed to open up UDP
464 to allow password-changing. This hasn't been an issue for me in the
past because, until very recently, I haven't been running a host-based
firewall on my own workstation. If I had been, then I'm sure my 1.3.4
kpasswd would have had the same problem. My test earlier today with a
1.3.4 kpasswd was from a different machine (still running 1.3.4) that
doesn't have such a firewall.
I realized all this when I discovered that 1.4.2 kpasswd worked fine from
my 1.4.2 KDC itself. I then ran a trace of kpasswd on my workstation and
saw that the 'permission denied' problem was coming when trying to write
to a socket for the actual password change.
