Why does sudo xhost throw an error on openSUSE, but su -c xhost does not?

Here are some things that work:

xhost
su -c xhost
su -c su logname -c xhost

Here are some things that do not work:

sudo xhost
sudo su logname -c xhost
sudo runuser -l logname -c xhost
sudo -u logname xhost

Those each threw the following error: access control enabled, only authorized clients can connect Does anyone have any idea why this is happening, or how I can use the xhost command in a script that my users will most likely be running with sudo?
