[Freeipa-users] stopping su -

[Steven Jones]

Hi,

I could do,

auth    required        pam_wheel.so    root_only use_uid

But I really want to do this with IPA  or I have to get on each server and add and remove admins by hand (hint 300 servers)...that is the idea of something like IPA for me....do it once centrally.

I assume simo's hint is,

 sudo -i su - oracle

I will have to experiment.

regards

I can't speak to whether it can or cannot be done centrally in any sort
of authoritative way, might be possible there are hbac setting for su
and I can't really answer your question about suing to oracle.
