Subject [jira] Commented: (GERONIMO-4846) form based security for the web application does not work with Jetty WADI clustering.
Date Wed, 16 Sep 2009 08:33:57 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-4846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755936#action_12755936
] 

Rex Wang commented on GERONIMO-4846:
------------------------------------

Form based security relies on the built in "j_security_check". Java EE Servlet spec has some
descriptions on this function, but not very detailed. Basically, all the mainstream web containers
have their implemetation on this. So, this is really vendor specific.
And it is not a problem when you keep session affinity. We have tested on both Jetty6 and
Jetty7, and they have the same behavior.
I plan to close this jira, any thoughts?

> This is a part of https://issues.apache.org/jira/browse/GERONIMO-4777,  the major issue
has been resolved with the patch from  	 Trygve Hardersen.  Opening this JIRA to track the
remaining problems.
> ----------------------------------------
> However it does not work when combined with form based security for the web application.
The first problem is that org.eclipse.jetty.security.authentication.SessionCachingAuthenticator$SessionAuthentication
and org.eclipse.jetty.security.authentication.SessionCachingAuthenticator are not serializable,
so they can not be sent across the network. I made these classes serializable, and then login
works as long as there is only one member in the cluster (well, not really a cluster...).
When there are multiple members in the cluster, login fails because there is no valid constructor
for org.eclipse.jetty.security.authentication.SessionCachingAuthenticator$SessionAuthentication.
I tried to add a default constructor, but it's an inner class, and it seems to me like theAuthenticator
and UserIdentity properties are required for it to work so I did not try to extract the class.
> As I said login works as long as there's only one member in the cluster, but logout does
not. Calling javax.servlet.http.HttpSession#invalidate() throws an exception, because the
curent session can not be found:
> java.lang.AssertionError: Session [org.apache.geronimo.clustering.wadi.WADISessionAdaptor@7f488ddb]
is undefined
> org.codehaus.wadi.replication.manager.ReplicationKeyNotFoundException: Key [ccge2q2w9dz2]
does not exist
> I am attaching the patch for the WADIJettyClusteringBuilder (WADIJettyClusteringBuilder.patch)
and a sample project JGS (jgs.tar.gz) that demonstrates the security problems I'm experiencing.
The web-formlogin-clustering-plugin of the JGS project uses form based security and WADI clustering.
The /customer page is protected, and to access it one must login with any username and password,
as long as they are the same. Use test/test for instance. To test session invalidation, manually
enter the URL /logout.
> It would be very helpful if someone can comment on the usability of WADI clustering in
combination with Jetty7. To me it seems like it has not been tested much, and I think going
back to Jetty6 again is the best option for us, unless the issues described above can be easily
solved.
> Thanks for your help!
