Sudo seems not to be working. I can switch to root with root credential but not via sudo.
$ uname -n
maltr004
$ whoami
rmandal
$ sudo su -
$ whoami
rmandal
$ date
Tue Oct 12 11:50:12 EDT 2021
$
$
As you can see after "sudo su - " the user is not switching to root. Can anyone help on this? what can be the reason?
