You can use find in subshell:
DISPLAY=:0 XAUTHORITY=$(find /var/run/xauth/ -name "A${DISPLAY}-*") \
import -window root iitdm.png

First, for XAUTHORITY should be:
XAUTHORITY=/var/run/xauth/A${DISPLAY}-*
This works:
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}-msFdGa import -window
root iitdm.png
These do not
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}-* import -window root
iitdm.png DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}* import
-window root iitdm.png
Of course, the one that does work requires lookup of the content of
/var/run/xauth/ after a reboot.
Second, I do not see in the man page that xwd
would accept the
environment variable XAUTHORITY or option like -auth or -xauth.
I don't know why the URL I was working from used xwd instead of import.
Another URL that fails to provide a way that works, it too is for gdm:
