request.getRemoteUser() returns invalid username on EAP 6.0.1.ER4.2 ------------------------------------------------------------------- Key: SECURITY-719 URL: https://issues.jboss.org/browse/SECURITY-719 Project: PicketBox Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Negotiation Affects Versions: Negotiation_2_2_1 Environment: EAP 6.0.1.ER4.2 SPNEGO setup with Kerberos Kerberos user: demo(a)LOCAL.NETWORK Reporter: Marek Posolda Assignee: Darran Lofthouse Fix For: Negotiation_2_2_2 It seems that JBoss negotiation 2.2.1.Final doesn't work correctly on EAP 6.0.1.ER4.2. I am able to reproduce issue with SecuredServlet from negotiation toolkit. I logged in through SPNEGO (Kerberos) and in SecuredServlet, I am seeing those outputs: request.getUserPrincipal() returns principal with name "demo(a)LOCAL.NETWORK" -> OK request.getRemoteUser() returns something like "dPC0cG6NhAUi88tSbvQar59M_1357729358922" -> FAILURE!!! SecurityContextAssociation.getSecurityContext().getSubjectInfo().getIdentities().next() also returns "dPC0cG6NhAUi88tSbvQar59M_1357729358922" => FAILURE!!! Note that JBoss Negotiation 2.2.1.Final works correctly on JBoss AS 7.1.3 but it failed only on EAP 6.0.1.ER4.2. The reason is not related to Negotiation itself, but due to changes in behaviour in related libraries like jboss-as-web and picketbox-infinispan. In NegotiationAuthenticator the call to JBossWebRealm: principal = realm.authenticate(username, (String) null); now returns JBossGenericPrincipal with username taken from calling username. So it's something like "dPC0cG6NhAUi88tSbvQar59M_1357729358922" as calling username is only placeholder computed from sessionId and system time. Previously the username was taken from principal of JAAS authenticated user, which correctly returned "demo(a)LOCAL.NETWORK". So the bug seems to be due to changes in JBossWebRealm and maybe also picketbox classes like JBossCachedAuthenticationManager (seeing that cache key is now also calling username instead of username of authenticated principal).
