Hi Mickael,

I mean that sc.getUserPrincipal().getName() returns distinguished name from 
certificate subject, not just "client" and "admin".

Regards,
Andrei.

Basically your configuration should work.
Possible issue is that sc.getUserPrincipal().getName() is not the same as 
configured user names: "client" and "admin".
It causes empty userRoles list from configured map in 
SimpleAuthorizingInInterceptor:
            List<String> userRoles = 
userRolesMap.get(sc.getUserPrincipal().getName());    
Could you check it in debugger?

Regards,
Andrei.

Yep, correct.
SAML has extensions mechanism, where it is possible to define additional 
attribute statements. 
In some scenarios it is really the case that STS service not only authenticate 
the user and issues SAML token with Authentication statement, but also maps 
user to role and inserts role as attribute statement in SAML. STS service has 
appropriate claims/attribute statements extensions points to do it (see as 
sample 
http://svn.apache.org/repos/asf/cxf/trunk/services/sts/sts-core/src/test/java/org/apache/cxf/sts/common/CustomClaimsHandler.java
 ).
Therefore WSS4JInInterceptors tries to get roles from the SAML.

You can follow this approach and extend STS to do user -> roles mapping.
Other option is to do it in own interceptor. As basis you can look 
JAASLoginInterceptor and RolePrefixedSecurityContextImpl that just adds ROLE_ 
prefix to user name and interprets it as role 
(http://svn.apache.org/repos/asf/cxf/trunk/rt/core/src/main/java/org/apache/cxf/interceptor/security/JAASLoginInterceptor.java
 ).

Andrei.

Hi Andrei,

Thanks for your helpful answer.

I'm trying to use the Interceptors provided by CXF but I get the following 
issue:

In the WSS4JInInterceptor, when the method doResults is called to construct the 
security result, at line 482, the condition 
o.get(WSSecurityEngineResult.TAG_SAML_ASSERTION) != null is false for me, so 
the createSecurityContext method is called without the roles (which causes to 
call createSecurityContext with null roles). So, when sc.isUserInRole(role) is 
called in AbstractAuthorizingInterceptor at line 100, it always returns false, 
so the call to isUserInRole(sc, expectedRoles, false) in 
AbstractAuthorizingInterceptor at line 84 also returns false, and the client is 
then never authorized.

I know that I'm missing something here related to the TAG_SAML_ASSERTION. Maybe 
the caller has to provide its role inside the SOAP message? If yes, I don't 
understand why, the caller should only know its identity, the roles is more for 
the server side which checks if the caller's identity is associated to an 
expected roles.

Thanks,
Mickael

Hi Mickael,

You can use CXF AbstractAuthorizingInInterceptor and 
SimpleAuthorizingInInterceptor as basis:
http://svn.apache.org/viewvc/cxf/trunk/rt/core/src/main/java/org/apache/cxf/interceptor/security/AbstractAuthorizingInInterceptor.java
http://svn.apache.org/viewvc/cxf/trunk/rt/core/src/main/java/org/apache/cxf/interceptor/security/SimpleAuthorizingInterceptor.java

Idea is the following: SimpleAuthorizingInInterceptor is configured with 
methods-roles map. Interceptor validates does user in given role have 
permissions to accessing method.

There is the sample configuration in
http://svn.apache.org/viewvc/cxf/trunk/systests/jaxrs/src/test/resources/jaxrs_jaas_security/WEB-INF/beans.xml

It can be a good starting point for your task.

Regards,
Andrei.

Subject: Authorization with CXF and WSS4J?

Hi,

I'm looking for a way to implement web service authorization with CXF but I 
can't find anything on the CXF documentation, nor on the web. I would like to 
define roles, and to specify for each web method which roles are authorized...
I've looked at the different WS-* support in the doc, especially WS-Security, 
WS-SecurityPolicy and WS-Policy but I don't understand how these can be use for 
authorization.

Please, provide me some links in the case it is possible.

Thanks
