Found out the following.
If you want to distribute free iBooks to students with Managed Apple IDs. You must allow the App Store on the iPad until the Managed Apple ID is registered. After the Managed Apple ID is registered, the App Store can be removed and iBooks downloaded.
Also found out that is one Profile allows the App Store and another Profile disallows the App Store, the Profile that disallows the App Store wins. Hate the way that Profiles are layered. Doesn't work well at all. There should be a passthrough (-) so that the Profile specific setting is ignored and will abide by another Profile with the setting specified (either Allowed or Disallowed). That would make it so much easier to layer Profiles.
