[jira] Commented: (GERONIMO-2687) All "default" Subjects should be obtained by logging in to a realm, not constructed explicitly

David Jencks commented on GERONIMO-2687:
----------------------------------------

rev 547163 fixes some problems related to who gets to deregister the default and run-as subjects.  The answer is, the ApplicationPolicyConfigurationManager does: it registers them when it starts and gets the run-as subjects from the CredentialStore, so it should deregister them when it stops.

> We have several places where we just construct a Subject for a default principal or some such.  This ties us to some very restrictive assumptions about what a principal is that are incompatible with e.g. triplesec.  Also it separates security management into maintaining the login backing store (e.g. ldap) and maintaining the deployment plan. 
> Instead, all these subjects should be obtained by logging into a realm.  To do this we need way to supply the appropriate credentials.
> I'm thinking of an interface
> public interface CredentialStore {
>     Subject getSubject(String realm, String id) throws LoginException;
> }
> that appropriate bits can use to get the subject they need.  The normal implementation can store credentials for the ids and log in to the realm indicated.  We can have a backwards-compatible implementation that constructs the subject as is done currently.
> Even better would be to have this accessible only through having some permissions.  However this would require starting the server to require credentials.  I'm not sure how to implement that or if it would have widespread support.
