Okay, thanks a lot.
Is there anything else that needs to be done to make getpwnam(),
getpwuid() and getgrouplists() use SSS from inside the container?
(Sorry if that question is stupid, but I don't have access to the
container now to try it.)
Hi,
no, as said calling authconfig/authselect in the container (or when
creating the container image) with the option to enabled SSSD should be
sufficient. Otherwise you have to modify /etc/nsswitch.conf and the PAM
configuration manually.
