What type of object can a Principal be in the application?

A Principal in the context of the application can refer to either a User or a Group. This is essential for managing permissions and access control within the application. By allowing both Users and Groups to be considered Principals, the application provides flexibility in organizing and managing access rights.

A User represents an individual with specific credentials and access privileges, while a Group serves as a collection of Users that can be assigned shared permissions. This dual capability allows for more efficient management of permissions, especially in environments where access needs to be granted or revoked for multiple users simultaneously. Thus, recognizing both Users and Groups as Principals facilitates clearer and more scalable permission management strategies.
