Distributing iPhone apps under Enterprise program

I'm trying t开发者_如何转开发o figure out more details on how apps are distributed to users when under the Enterprise developer program. The Enterprise Deployment Guide states:

If you develop an application that you want to distribute yourself, it must be digitally signed with a certificate issued by Apple. You must also provide your users with a distribution provisioning profile that allows their device to use the application.

What I want to know is how is the provisioning profile is created so that a specific device is allowed to use the app? Is this done by adding device UDIDs into the profile as per the standard developer program? Or some other means?

Provisioning profiles are managed thanks a website provided by Apple. It will be possible to generate and download Provisioning profiles from this website.

Then, if you sign an application with the Enterprise program licence, you will be able to install it on any device. You just have to send to the user your application and the provisioning profile.

Regards,
