org.apache.jackrabbit.api.security.principal.PrincipalManager
This interface defines the principal manager which is the clients view on all principals known to the repository. Each principal manager is bound to a session and is restricted by the respective access control. The principal manager in addition provides basic search facilities.
A {@link Principal} is an object used to connect to any kind of security mechanism. Example for this are the {@link javax.security.auth.spi.LoginModule login modules} that use principalsto process the login procedure.
A principal can be a member of a {@link Group}. A group is a principal itself and can therefore be a member of a group again.
Please note the following security considerations that need to be respected when implementing the PrincipalManager: All principals returned by this manager as well as {@link Group#members()} must respect access restrictionsthat may be present for the Session this manager has been built for. The same applies for {@link #getGroupMembership(Principal)}.
