[Freeipa-users] sudo NOPASSWD for a single command

[Auerbach, Steven]

We have a script stored on a particular server in our realm that executes a number of non-privileged commands and are wanting to add /sbin/vgs command. The script uses SSH to then execute the same set of commands on all the servers in the realm.

The owner of the script is in the administrator group and there are sudoer commands for the administrator group in general. We need to place a rule for this one command for either this group or the script owner to run NOPASSWD.

Where and how would I specify that in the IPA admin console?

Have you tried creating your command in IPA as "NOPASSWD: /sbin/vgs" (Policy -> Sudo -> Sudo Commands)?

[Auerbach, Steven]

Yes, I implemented in Policy -> Sudo -> Sudo Commands as:
Sudo Command: NOPASSWD: /sbin/vgs

The script (executed by a non-root, administrative group user on an enrolled host) specifies:

.
hostname >> statresults.txt
cat /etc/redhat-release >> statresults.txt
uname -r >> statresults.txt
printf "\n " >> statresults.txt
sudo vgs >> statresults.txt

..
Running the script I still was prompted for a password. So I guess this does not work.

sudo vgs >> statresults.txt

should be sudo /sbin/vgs >> statresults.txt since that is what sudo
allows. its almost like exact match for strings.

NOPASSWD is used in /etc/sudoers. In IPA, create a sudo option
"!authenticate" instead.
