OpenLDAP conditional sudo based on server tag
26 March 2026 @ 8:00 am
Imagine Host1 belongs to groupA, and Host2 belongs to groupB. I would like to add Alice to groupA and to groupSudo - so she can execute sudo commands on Host1, while she would not have sudo access on host2, but she can still login there as simple user.
Similarly I want to assign Bob to groupB and groupSudo - that would give him sudo only on Host2. And Cynthia to all 3 groups so that she gets sudo everywhere.
I'm struggling to finding this solution though. I did find a solution where I would restrict Alice login to Host2 entirely, by configuring sssd to not allow logins if not in groupB. HCISSP Preparation Strategy for Security Topics – Need Advice [closed]
