Interestingly, gksudo does not seem to have a verbosity option like -v.  It
DOES have --debug so I tried that and got:

larry at ldesk:~$ gksudo --debug "gedit /boot/grub/menu.lst"
xauth: /tmp/libgksu1.2-1yI5Y8/.Xauthority
cmd[0]: /usr/bin/sudo
cmd[1]: -H
cmd[2]: -S
cmd[3]: -p
cmd[4]: GNOME_SUDO_PASS
cmd[5]: -u
cmd[6]: root
cmd[7]: --
cmd[8]: gedit
cmd[9]: /boot/grub/menu.lst
buffer: -GNOME_SUDO_PASS-
Yeah, we're in...
(gedit:10011): GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols
specified are supported and host-based authentication failed.
xauth: /tmp/libgksu1.2-1yI5Y8/.Xauthority
xauth_env: /home/larry/.Xauthority
dir: /tmp/libgksu1.2-1yI5Y8


Yes, I agree, the original message, still output, would seem to indicate
failure even though listed as a warning.  The additional debug info clearly
says it DID work.  Curioser and curioser.

The only other thing I found, and I don't see how it would relate to
authentication, is that the root user environment don't not have a DISPLAY
variable.
