x11vnc can't find MIT-MAGIC-COOKIE

When I run x11vnc from ssh as the user that’s controlling the local X11
session, I get

Code:

03/01/2012 13:59:59 x11vnc version: 0.9.4 lastmod: 2008-09-16
No protocol specified

03/01/2012 13:59:59 ***************************************
03/01/2012 13:59:59 *** XOpenDisplay failed (:0.0)

*** x11vnc was unable to open the X DISPLAY: “:0.0”, it cannot continue.
*** There may be “Xlib:” error messages above with details about the failure.

Some tips and guidelines:
…

and the message continues telling me to use -auth, -findauth, etc. If I
sit down at the local session, it starts fine.

Running -echo $XAUTHORITY- in the local session tells me my XAUTHORITY
file is “/var/run/gdm/auth-for-bobpaul-mZ1BwR/database”. Running -x11vnc
-auth /var/run/gdm/auth-for-username-mZ1BwR/database -display :0.0-
results in the same error above. Additionally, xdpyinfo doesn’t work
remotely:

Code:

bobpaul@lonepine:~>env XAUTHORITY=/var/run/gdm/auth-for-bobpaul-mZ1BwR/database xdpyinfo -display :0
No protocol specified
xdpyinfo: unable to open display “:0”.

The file is definitely owned by the user:

Code:

-rw------- 1 bobpaul bobpaul 54 2011-12-26 10:29 /var/run/gdm/auth-for-simetkos-mZ1BwR/database

My understanding was if ssh’d using the same user (bobpaul) that’s
controlling the local session AND provided the path to the
MIT-MAGIC-COOKIE file, that really nothing else could go wrong.

It’s SLES 11, 64bit
Code:
