During installation of Server Express, I am asked "Do you want only superuser to access the License Admin System"?

What happens if I say Yes?   Is this irreversible?

Saying "Yes" invokes a chmod 700 on the directory in which the License Management System is installed. Since the install script is executed with root permissions, root will be the owner and will have sole permissions to the directory. To reverse this, simply chmod the mflmf directory to meet your permissions requirements.
