Yes, they surely can. Specifically, an authenticated JAAS Subject can
have multiple Principals associated with it upon login/authentication
(via JAAS...this has nothing to do with ECF per se). The ECF ID
interface (org.eclipse.ecf.core.identity.ID) extends
java.security.Principal, meaning that all ECF IDs are also potentially
Principals associated with a JAAS Subject. They would then be available
via methods like subject.getPrincipals() and/or getPrincipals(Class c).
One thing this depends upon is the ability for plugins (like ECF or
others) add Principals to an authenticated Subject during
login....hopefully without writing a separate LoginModule. There is an
Equinox security incubator bug here to that effect:

This is exactly the intention/design...by using the Principal interface
as super interface for IDs, and thereby enabling using
Note also that ECF's Namespace extension point allows plugins to create
their own Namespaces (Namespaces are factories for creating
Principals/IDs of a certain type/types).
