sudo questions
Bonjour,
For some unknown reason I did not activate the root account during the
installation. I activated it from a user account, say John Doe.
Now John Doe can become root anytime and do anything on my machine.
How can I deactivate this? I have seen that John Doe is a member of
almost all groups in /etc/group and /etc/gshadow...
Is there a simple method to remove John Doe from these files and are
there other files to modify?
I asked a question about this inconvenience of the sudo way to activate
root account: lightdm accepts to login root for a graphical session, I
found a method to forbid this: add this line in /etc/pam.d/ligthdm:
auth required pam_succeed_if.so user != root quiet
I don't understand this "fashion": sudo and no root account.... It is
the same under ubuntu. What for?
Thanks.
