RHEL5/6: Why does rhn-migrate-classic-to-rhsm require a user to be the org_admin ?

Issue

• Why does rhn-migrate-classic-to-rhsm require a user to be the org_admin?
• RHEL5 or 6, hooked up to RHN-classic can not be transitioned to subscription management if the user is no org_admin. That is undesirable, especially in big accounts with hundreds of users.
