<div class="jive-rendered-content"><p>Hi</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've been looking recently at resolving JBWS-2210 [1].</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The issue is to do with the fact that a WS-Security UsernameToken can not be currently used in JBoss CXF to integrate with the JBoss security subsystem for authentication and authorization decisions be made.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've done some initial changes in CXF and started a discussion on the cxf dev list [2].</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Here is the summary of the proposed approach.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The idea is to override a CXF WSS4JInInterceptor and provide a CallbachHandler to the WSS4J module which will ensure that an authentication occurs but also that a current SecurityContext is properly populated. The CXF interceptor which overrides CXF WSS4JInInterceptor is an abstract one [3], its job is to ensure that irrespectively of whether a current password is digested or not, the concrete subclass is requested to authenticate and populate a Subject.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>CXF also includes an abstract AuthorizingInInterceptor[4] which requests a subclass for a list of expected roles and asks SecurityContext if a user is in role.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Given the above, here's how I'm thinking of resolving JBWS-2210 :</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>- provide a CXF interceptor (to be included in JBoss CXF) which will extend [3] and delegate to JBoss AuthenticationManager to populate a Subject</p><p>- provide a CXF interceptor (to be included in JBoss CXF) which will extend [4] and retrieve a list of expected roles;</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>JBoss CXF WS-Security UsernameToken-aware endpoints will include the above two interceptors if the authentication & authorization is needed.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>At the moment I'm working on a system test validating the above approach.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>If you have any comments then please let me know</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>cheers, Sergey</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span>[1] </span><a class="jive-link-external-small" href="https://jira.jboss.org/jira/browse/JBWS-2210" target="_blank">https://jira.jboss.org/jira/browse/JBWS-2210</a></p><p><span>[2] </span><a class="jive-link-external-small" href="http://old.nabble.com/Using-WS-Security-UsernameToken-to-authenticate-users-and-populate--SecurityContexts-td28165583.html" target="_blank">http://old.nabble.com/Using-WS-Security-UsernameToken-to-authenticate-users-and-populate--SecurityContexts-td28165583.html</a></p><p>[3] <a class="jive-link-external-small" href="http://svn.apache.org/repos/asf/cxf/trunk/rt/ws/security/src/main/java/org/apache/cxf/ws/security/wss4j/AbstractWSS4JSecurityContextProvidingInterceptor.java">http://svn.apache.org/repos/asf/cxf/trunk/rt/ws/security/src/main/java/org/apache/cxf/ws/security/wss4j/AbstractWSS4JSecurityContextProvidingInterceptor.java</a><br/> [4] <a class="jive-link-external-small" href="http://svn.apache.org/repos/asf/cxf/trunk/rt/core/src/main/java/org/apache/cxf/interceptor/security/AbstractAuthorizingInInterceptor.java">http://svn.apache.org/repos/asf/cxf/trunk/rt/core/src/main/java/org/apache/cxf/interceptor/security/AbstractAuthorizingInInterceptor.java</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p></div>
