Subject [jira] Commented: (GERONIMO-1440) JAASJettyRealm not shared enough
Date Thu, 12 Jan 2006 08:07:23 GMT
    [ http://issues.apache.org/jira/browse/GERONIMO-1440?page=comments#action_12362520 ] 

David Jencks commented on GERONIMO-1440:
----------------------------------------

The previous solution is too annoying and not very accurate.  The presence of realm-name in
the descriptor doesn't really mean anything, and we should not be assuming security is intended
based on its presence.  Perhaps if login-config is present we require a security-realm-name?

Anyway, this adds some useless security info to the jetty apps to let them deploy.

> There are a bunch of problems that lead back to missing JAASJettyRealms or multiple "equal"
JAASJettyRealms.
> A JAASJettyRealm has an (external) realm name from the web.xml and an internal geronimo
realm name and a map of user name to principal (which includes the Subject for that user)
for logged in users.  If you supply a (internal) security realm name, a JAASJettyRealm is
registered with the HTTPContext and used for authentication, reauthentication, etc.  If you
don't supply a security realm name, but there is a realm name, then jetty tries to get the
realm from the JettyServer.  Here are some problems:
> 1. we never register our JAASJettyRealms with JettyServer, so if you don't supply a security
realm name you eventually get NPEs if the app calls isUserInRole etc etc.
> lets assume we fix (1)
> 2. If you have 2 apps  A and B deployed with the same external realm name and internal
realm name, only the last to start is registered with  the JettyServer.  Any other app C using
the same realm name but no internal realm name will get the second realm.  If we did a x-context
dispatch from the first app A to C C will be using the realm from B.
> I think that there should only be one JAASJettyRealm per external realm name, based on
servlet spec 2.4 section 12.6.  If you disagree, please say why :-).
