10 - System Management
10.1 - Why does it say that I'm in the wrong group when I try to 
su root?
On OpenBSD, users who are in the 
wheel
group are allowed to use 
su(1)
 to become root. Otherwise, the 
user will receive an error. 
If you are creating new users with 
adduser(8)
, you can add them to the 
wheel
group by answering 
"wheel" at the "
Invite user into other groups:
" prompt. Existing users must be added to the 
wheel
group by hand. Here is an example of a 
/etc/group
entry which has had the user ericj added to 
the 
wheel
group: 
wheel:*:0:root,ericj
If you want to give access to superuser privileges without adding users to the 
wheel
group, use 
sudo(8)
.
