Hello Andy & Josh,
Yes, the password is not set because the user cannot be added when the
reservation is made.
Is there something special I needed to set when I first captured the Ubuntu
Image ?
Here is a snippet of the vcld log:

It sounds like the password isn't getting set. Please send the vcld.log output
for one of your problematic reservations. I'll take a look at it.
One thing to check would be to try to log in using the credentials displayed on
the page directly to the VM's console. This will determine if SSH has anything
to do with it.
Regards,
Andy

Al,
I'd suggest logging in to the VM as root from the management node and checking
log files for why it says the user is being denied access. In additional to
checking log files, another thing you can do that can help with debugging is
to stop the external sshd process and then run it in debugging mode. You can
stop the existing process with
initctl stop ext_ssh
Then, run it again with
/usr/sbin/sshd -d -f /etc/ssh/external_sshd_config
This runs sshd in the foreground with debug output enabled. Also, you can
specify multiple "d" options to increase the verbosity of the debug output
(i.e. -dd or -ddd).
After doing the above, you can then try to log in again from another console
to get a better idea of why it is failing.
