[sudo-users] script runs using sudo but not as root

I tried to eliminate some of the details to help make the problem more  

The script is the run_cfengine.sh script which as you can expect runs  
GNU's cfengine on the client. These systems are part of a cluster, up  
until recently they were all running CentOS 4.3. I upgraded 8 of the  
nodes to 64-bit CentOS 5.2. All the files that cfengine touches reside  
on a NFS mounted disk array.

The strange thing is that the cfengine configuration wasn't touched,  
as wasn't the files that are pushed over to the cluster nodes (eg. the  
sudoers file). The 64-bit nodes cfengine script works, but the older  
32-bit nodes gotten broken somehow in the process.

The problem is more of "what is sudo doing right?", because even if  
I'm logged in as root the script fails when I try to run it, but if I  
run it using sudo it runs without a problem. As my first email showed  
hopefully with the included sudoers file, our sudo setup is as basic  
as it can get, root and our three administrators have all sudo rights.  
No changes to how paths are inherited or anything, sudo is running  
under the environment of the calling user as per default.
