SharePoint2013 Note on AppPrincipal

AppPrincipal Indicates what kind of authentication an app requires and what type of app it is.

Various types of AppPrinciplas are:-
1. Internal: This is the default for SharePoint Hosted apps. Indicates that no external authentication is required.

Some times a cloud-hosted app can use "internal" auth when calling back using cross-domain library. To achieve this you should configure AppPrincipal  with "Internal" element with attribute "AllowedRemoteHostUrl".

2. RemoteWebApplication: This is the default for a Provider Hosted apps. Indicates that app requires external authentication like Oauth
3. AutoDeployedWebApplication: Indicates that App is autohosted and requires external authentication.
