Err, I wasn't sure but this didn't sound right to me, I am sure a shell 
is not required for program execution, so I tested it. After 
/bin/falseing and locking the nagios account, the service check I have 
sudo NOPASSWDed still worked, and I cronned a job to get the date which 
ran every minute and output to a temp file. So it would seem that this 
is not correct. A valid shell is not required.
