  1. Ensure the Package-x-generic-16.pngrealmd package is installed on the test client (e.g. su -c 'dnf install realmd')
  2. Remove the Package-x-generic-16.pngsssd, Package-x-generic-16.pngfreeipa-client and Package-x-generic-16.pngsamba-client packages (e.g. su -c 'dnf remove sssd samba-client') from the test client, they should be installed by realmd if necessary
  3. Unless you wish to test pending updates, disable the 'updates-testing' repository so realmd does not install packages from it: su -c 'dnf config-manager --set-disabled updates-testing'
  4. Install the Package-x-generic-16.pngkrb5-workstation package to get the 'klist' and 'kinit' tools.
