Sudo Password Prompt over SSH
I am not sure what I am missing here. I have the following identical entry in /etc/sudoers on multiple Red Hat 6.4 servers.

Code:
icinga  ALL=NOPASSWD:/usr/bin/yum --security --exclude\="kernel*" check-update

On one server when I enter the command over SSH as follows it works fine.
Code:
ssh -t -q icinga@$sshhostname sudo /usr/bin/yum --security --exclude\=\"kernel*\" check-update

On a few servers I am prompted for the sudo password when I issue the command.
Code:
[sudo] password for icinga:

If I ssh to the server that is having the issue and execute the sudo command I am not prompted for a password. What am I missing here? the /etc/sudoer files are identical on a server that is working. Is this something with SELinux that I am perhaps missing?

yum-cron

yum-cron(8)															       yum-cron(8)

NAME

       yum-cron - an interface to convieniently call yum from cron

SYNOPSIS

       yum-cron [config-file]

DESCRIPTION

       yum-cron  is  an  alternate  interface to yum that is optimised to be convenient to call from cron.  It provides methods to keep repository
       metadata up to date, and to check for, download, and apply updates.  Rather than accepting many different command line arguments, the  dif-
       ferent functions of yum-cron can be accessed through config files.

       config-file  is	used  to optionally specify the path to the configuration file to use.	If it is not given, the default configuration file
       will be used.  It is useful to be able to specify different configuration files for different use cases.  For  example,	one  configuration
       file  might  be set to update the repository metadata, and a line could be added to the crontab to run yum-cron frequently using this file.
       Then, another configuration file might be set to install updates, and yum-cron could be run from cron using this file just once each day.

FILES

       /etc/yum/yum-cron.conf
       /etc/yum/yum-cron-hourly.conf

SEE ALSO

       yum (8)

AUTHORS

       See the Authors file included with this program.

BUGS

       There of course aren't any bugs, but if you find any, you should email
	the mailing list, yum@lists.baseurl.org, or consult bugzilla.
