sudo using at failing.

Yep, It's definitely in the path. I've tried it with and without the full path in the command line. In my haste in posting yesterday.
I forgot to mention that FTP users seem to have no problem here. I'm using vsftp as the server software. All instances of the at command are spawned as the user ftp-files, an internal user with shell privileges. Users that access the site via https however spawn all processes as the user they login as. I.E. external users with no shell privileges. Again the weird thing is that the immediate removal works at doesn't. Both means of access trigger the same script file, the only difference is the user name.
I've also noticed that depending on whether or not I use sudo for the at command itself the user under which it's spawned will change as well.
If nothing else, I've at least got to look forward to the "Brick Wall" until I get this figured out.
-----Post Update-----
It may not be right, but I've found a work around.
I had to call the script that spawns the at command via sudo. For whatever reason calling the at command directly wouldn't work sudo or not. I even tried just echoing text to a file. Nothing... Nothing in /var/log/anything. Just nothing.
Backing up one script and making the sudo call there worked. Although I still want to figure out why the direct call didn't work, I'll have to put it aside for now and finish my task.
Thanks for the input.

viewsudo
VIEW-OS(1) General Commands Manual VIEW-OS(1) NAME
viewsudo - execute a command as another (virtual) user SYNOPSIS
viewsudo [-g groupname|#gid] [-u username|#uid] command DESCRIPTION
viewsudo allows a user to execute a command as the superuser or another user in View-OS. OPTIONS
viewsudo accepts the following command line options: -g group Normally, viewsudo sets the primary group to root. The -g option causes sudo to run the specified command with the primary group set to group. To specify a gid instead of a group name, use #gid. When running commands as a gid, many shells require that the '#' be escaped with a backslash ('[u2019]). If no -u option is specified, the command will be run as the invoking user (not root). In either case, the primary group will be set to group. -u user The -u option causes viewsudo to run the specified command as a user other than root. To specify a uid instead of a user name, use #uid. When running commands as a uid, many shells require that the '#' be escaped with a backslash ('[u2019]). RETURN VALUES
Upon successful execution of a program, the exit status from viewsudo will simply be the exit status of the program that was executed. SEE ALSO
