[Freeipa-users] Freeipa Sudo / sudoers.d / nopasswd

[Ash Alam]

Based on (How to troubleshoot Sudo)

- Maybe i miss spoke when i said it fails completely. Rather it keeps
asking for the users password which it does not accept.
- I do not have sudo in sssd.conf
- I do not have sudoers: sss defined in nsswitch.conf
- Per Fedora/Freeipa doc (Defining Sudo), its not immediately clear if
these needs to be defined
- If this is the case then adding them might resolve my issues.
- for the special sudo rule(s). is there any way to track it via the gui? I
am trying to keep track of all the configs so its not a blackhole for the
next person.

- This is what it looks like on the web gui

- This is what a clients sssd.conf looks like
