Why is it a problem for console access? :-)
All people account are managed in a
ldap, only root has a password and can be used in last resort.
The most obvious case in when something is wrong with sssd, letting us with only local
users.
We could set up a local account for that purpose but it wouldn't fit easily with
PCI-DSS.

Is
there a way to get a specific information when this access is used ?
Maybe not all what was done but at least that someone used this entry.
If you need to know the commands & changes made by root, then you
probably need to use pam_tty_audit to enable tty auditing for su and sudo.
> Would you recommend to forbid root access even in console ?
Yes. Who is root? Who was root 4 years ago? By logging in with your account
and then changing to root, the audit system can track who root is. The only
time I can think of where you wouldn't want this tracking is when the system
is in single user mode. (Because auditd doesn't normally start in single user
mode.)
