In this document we show how to use PicketLink STS to validate SAML assertions and authenticate EJB clients.
Required software: JDK 6, PicketLink version 1.0.3 or superior. (Feature available starting 1.0.3.CR2)
The client must first obtain the SAML assertion from PicketLink STS by sending a WS-Trust request to the token service. This process usually involves authentication of the client. After obtaining the SAML assertion from the STS, the client includes the assertion in the security context of the EJB request before invoking an operation on the bean. Upon receiving the invocation, the EJB container extracts the assertion and validates it by sending a WS-Trust validate message to the STS. If the assertion is considered valid by the STS (and the proof of possession token has been verified if needed), the client is authenticated.
On JBoss, the SAML assertion validation process is handled by the SAML2STSLoginModule. It reads properties from a configurable file (specified by the configFile option) and establishes communication with the STS based on these properties. We will see how a configuration file looks like later on. If the assertion is valid, a Principal is created using the assertion subject name and if the assertion contains roles, these roles are also extracted and associated with the caller's Subject.
And this is the implementation class:
The session defines four methods: invokeRegularMethod (available to both Administrators and RegularUsers), invokeAdministrativeMethod (available to Administrators only), invokeUnprotectedMethod (available to all authenticated clients), and invokeUnavailableMethod (annotated with @DenyAll and thus unavailable to all roles).
Besides the sample session classes, our ejb3-sampleapp.jar contains the application policy definition for the EJBs:
The policy defines two login modules: SAML2STSLoginModule and UsersRolesLoginModule. The first will be responsible for validating the assertion with the STS in order to authenticate the client, while the second will be responsible for retrieving the client's roles from a properties file. In order to validate the SAML assertions, SAML2STSLoginModule needs information about the STS, like its endpoint URL, service name, port name, etc. This information is supplied by the sts-config.properties file:
The last two properties specify the username and password that will be used to authenticate the JBoss server to the STS when the WS-Trust validate message is dispatched. In other words, SAML2STSLoginModule needs to authenticate to the STS when validating the SAML assertions and these properties specify the username and password that will be used for that.
In our sample applications we will have three users (UserA, UserB, UserC), each with different roles. The ejb3-sampleapp-roles.properties file specifies the roles that have been assigned to each user:
As we can see, UserA is both a RegularUser and Administrator, so he should be able to call all methods except for invokeUnavailableMethod. UserB is a RegularUser, so he should be able call invokeRegularMethod and invokeUnprotectedMethod methods. UserC is a Guest and should be able to invoke only the unprotected method of our sample EJB.
For the sake of completeness, here we can see the jboss.xml file of our ejb3-sampleapp.jar:
All the configuration files can be found in the ejb3-sampleapp.jar that has been attached to this document.
This is the content of the STS web.xml:
STS callers must all have the STSClient role in order to send a WS-Trust request to the STS.
The STS security domain is specified by the jboss-web.xml file:
The application policy for the sts-domain is defined in the sts-jboss-beans.xml file:
The sts-users.properties specify the username/passwords of the STS callers:
The sts-roles.properties specify the roles of the STS callers:
Notice that the JBoss user represents the JBoss server during the SAML validation process. All other users are the clients of the EJB3 sample application - they send a message to the STS to acquire a SAML assertion before calling the methods on the EJB3 application.
As we can see, the assertion is first obtained using the WSTrustClient API. Once the assertion has been acquired, we use the SecurityClient API to push it to the client-side security context. Then we attempt to call all methods on the sample EJB3 session and print the results of these calls.
After copying the required PicketLink jars and deploying the sample application and the STS war, start your JBoss partition. If everything is ok, you should see something like the following in the log:
In order to compile the sample client application, you need to have ejb3-sampleapp.jar, picketlink-fed-1.0.3.jar (both attached in this document), and jbossall-client.jar (found in JBOSS_HOME/client) in your classpath. If using an IDE like Eclipse, all jars referenced by jbossall-client.jar will be automatically included in the classpath. If not, you may need to add these jars manually.
In order to run the client, all you have to do is specify the aforementioned classpath:
If everything has been configured and deployed properly, you should see the following output:
As we can see, each user had access to the expected methods. Authentication was performed by the SAML2STSLoginModule, which validated the supplied assertion with PicketLink STS, and the roles were provided by the UsersRolesLoginModule.
The remote and home interfaces look as follows:
And here we can see the implementation class:
The application policy definition (ejb2-sampleapp-jboss-beans.xml), the properties files used by the UsersRolesLoginModule, the STS configuration file, and the META-INF/jboss.xml file are all very similar to the ones found in the EJB3 example. For this reason we are not going to show them here.
Now, the authorization rules must be defined in the META-INF/ejb-jar.xml deployment descriptor:
As we can see, the invokeUnprotectedMethod is available to all roles. The Administrator role can call all methods on the bean except for invokeUnavailableMethod, which is in the exclude-list section. The RegularUser role is allowed to call only the invokeRegularMethod method besides the unprotected method.
In this case we are using the JndiLoginInitialContextFactory to set the SAML assertion in the security context just to show an alternative to the SecurityClient API. The JndiLoginInitialContextFactory gets the principal and credentials from the InitialContext properties and pushes them to the security context.
NOTE: The JndiLoginInitialContextFactory approach doesn't work for EJB3 beans on JBoss AS 5.1.0.GA. An issue (JBAS-7010) has been flagged and a fix is available for JBoss 5 EAP and JBoss AS 6. So if you are using JBoss AS 5.1.0.GA make sure to use the SecurityClient API to invoke EJB3 beans using SAML.
In order to compile the EJB 2 sample client application, you need to have ejb2-sampleapp.jar, picketlink-fed-1.0.3.jar (both found in this document), and jbossall-client.jar (found in JBOSS_HOME/client) in your classpath. If using an IDE like Eclipse, all jars referenced by jbossall-client.jar will be automatically included in the classpath. If not, you may need to add these jar manually.
In order to run the client, just specify the aforementioned classpath:
If everything has been configured and deployed properly, you should see the following output (similar to the output produced by the EJB3 client application we've shown before):
Required software: JDK 6, PicketLink version 1.0.3 or superior. (Feature available starting 1.0.3.CR2)
Process Overview
The following picture illustrates the process of using SAML assertions to authenticate clients of EJB applications:
EJB3 Integration Example
In this section we present a sample EJB3 application that authenticates clients by validating their SAML assertions with PicketLink STS. The deployments for both the EJB3 application and the STS can be found attached in this document.EJB3 Sample App
Our EJB3 application consists of a simple stateless session bean. The session interface can be seen bellow:/*

PicketLink STS
Our PicketLink STS application is a tweaked version of the picketink-sts.war file that is available in the PicketLink project downloads page. More specifically, we created a new security domain for the STS in jboss-web.xml, included an application policy for the new domain that uses the UsersRolesLoginModule to authenticate STS clients, included the users and roles properties files, and changed the required role in web.xml to STSClient.

Client Application
The client application for the EJB2 example is also very similar to the one used to test the EJB3 SAML integration. The main differences are the lookup code and the way we use to establish the client-side security context./*

* This class tests the usage of SAML assertions to authenticate clients of EJB2 applications on JBoss. This is
* accomplished by having the client first obtain a SAML assertion from the PicketLink STS service and then use
* the assertion as the credential when calling the protected EJB2.
*
*
* The protected EJB3 application used in this test has configured the {@code SAML2STSLoginModule}. This login
* module sends the SAML assertion to the STS for validation in order to authenticate the caller. A second login
* module, {@code UsersRolesLoginModule}, has been used to provide the client's roles.

} Deploying and Running the EJB2 Sample Application on JBoss AS5
If the PicketLink libs haven't been installed yet, you need to do this before deploying the sample application and the STS. This is accomplished by copying picketlink-fed-1.0.3.jar and picketlink-bindings-jboss-1.0.3.jar (both attached to this document) files to the JBOSS_HOME/server/partition/lib folder. After installing the required PicketLink libs you must copy the ejb2-sampleapp.jar and picketlink-sts-1.0.0.war to JBOSS_HOME/server/partition/deploy.java -cp CLASSPATH test.SAMLEJB2IntegrationTestInvoking token service to get SAML assertion for UserA
