  5. Randomize Kerberos password ON ALL KRB SERVERS (kadmin.local -p YOU_admin -q "cpw -randkey USER_admin")
  6. Randomize user.daemon Kerberos password ON ALL KRB SERVERS (kadmin.local -p YOU_admin -q "cpw -randkey USER_admin/daemon")

3. Changing system passwords

  1. On all hosts: sudo usermod -p '$1$...md5hash' root

  2. ssh root@ or admin@kvm.hcoop.net, run 'setup', choose S, type in new password twice, choose W. (KVM will reboot to reload pw)

  3. ssh admin@mire-sp.hcoop.net, run 'access update password -u admin', and also 'access get users' to make sure there are no accounts besides 'admin'
