I connect from my Windows box to a AIX 5.3 box using SecureCRT, which
allows the transfer of X11 packets to my local box.

When I log in as myself into the box, with my local Cygwin-provided X
server running, I can display windows perfectly fine.

However, if after logging in, I then "sudo" to an administrative
account and then try to run something that tries to display windows,
it says that it can't connect.

I tried doing "env | sort" from both my user account and the
administrative account, to compare the differences.  On the admin
shell, I set the following env vars from their value on my user
account:

DISPLAY, SSH_AUTH_SOCK, SSH_CLIENT, SSH_CLIENT, SSH_CONNECTION,
SSH_TTY

However, it still fails to connect.  I imagine that one of these
variables is "tied" to my user account somehow, and won't work if I
just copy the value over (probably a good idea :) ).

So, what can I do to facilitate this connection from the admin account
to my local box's X server?

export DISPLAY?

I exported all of those variables I indicated that I set, including
DISPLAY.- Hide quoted text -

- Show quoted text -

before you sudo:
"xauth list"
copy that, then sudo,
as new user, "xauth add <the output of the above xauth list>"
"export DISPLAY=" the original DISPLAY variable, which is also in the
output of the xauth list command

voila
.
