CompTIA Linux+ XK0-006 (V8) Practice Question

A RHEL 9 server has been joined to the corp.example.com Active Directory realm with realmd, and domain users are authenticating through SSSD. A new policy states that only members of the AD security group LinuxAdmins may obtain an interactive login on this host. The control must be implemented in SSSD (not in PAM or sshd).

Which modification to /etc/sssd/sssd.conf will enforce the requirement after the file is saved and SSSD is restarted?

  • Set enumeration = true in the [sssd] section so SSSD can list the LinuxAdmins group

  • Add simple_allow_groups = LinuxAdmins in the domain stanza and leave the existing access_provider unchanged

  • Under [domain/corp.example.com] add: access_provider = ad ad_access_filter = (memberOf=CN=LinuxAdmins,OU=Groups,DC=corp,DC=example,DC=com)

  • Disable credential caching by setting cache_credentials = false in the [sssd] section
