Hi,
We use Active Directory to manage our Linux access including SUDO permissions.
We need to have a particular account run a passwordless command. I created a new sudoRule in AD, added the following:
sudoCommand /bin/systemctl restart wildfly.service sudoHost +DevTestLinuxServer (our group of servers) sudoOption !authenticate sudoOrder 1 sudoUser svc_Jenkins_DTS
From what I'm reading, sudoOrder should be 0 when not defined, which it isn't in the other sudoRoles. So with this having a sudoOrder 1, it should take precedence when there's more than one match for the command. The other sudoRole is ALL:ALL, but requires a password, and that one works fine.
On the client side, logged in as svc_Jenkins_DTS, I see the following in the sudo log:

So it knows of both rules, and sorted them properly.
But doing a sudo -l showing the following:
[svc_jenkins_dts@la-1dglsesgap01 ~]$ sudo -l [sudo] password for svc_jenkins_dts: Matching Defaults entries for svc_jenkins_dts on la-1dglsesgap01: !visiblepw, always_set_home, match_group_by_gid, env_reset, env_keep="COLORS DISPLAY HOSTNAME HISTSIZE KDEDIR LS_COLORS", env_keep+="MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE", env_keep+="LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES", env_keep+="LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE", env_keep+="LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY", secure_path=/sbin:/bin:/usr/sbin:/usr/bin
User svc_jenkins_dts may run the following commands on la-1dglsesgap01: (ALL) ALL
So 1) why does it not show in the list it can run the command 2) why does it keep prompting for a password when I try to run the command
Thanks!
