About invitations for new users
When you use built-in authentication for your GitHub Enterprise Server instance, each person creates a personal account from an invitation or by signing up. 默认情况下，未经身份验证时可以访问实例的人员可以在实例上创建新的个人帐户。
You can disable unauthenticated sign-ups and require an invitation to create a new user account on your instance. For more information, see "Disabling unauthenticated sign-ups."
Alternatively, you can configure external authentication for your GitHub Enterprise Server instance. If you use external authentication, you must invite people to use your instance through your authentication provider. For more information, see "About authentication for your enterprise."
