By default, on FreeBSD Systems, switching to root (su root) is disabled.
In this article I will show you how to allow a normal user to su root.
If you try, you get this error:
$ su -
su: Sorry for normal user account.
To give a normal user su root priviledge, you have to add him to the wheel group (which is root’s group):
# pw usermod your_user -G wheel
To test if this works:
# groups your_user
your_user wheel
This is it.
If you want to enable all the normal user to switch to root, comment (add # in front of the line) this line in /etc/pam.d/su:
auth requisite pam_group.so no_warn group=wheel root_only fail_safe ruser
This is how the line should look like after being commented:
#auth requisite pam_group.so no_warn group=wheel root_only fail_safe ruser
