ejb-security-context-propagation: Demonstrate security context propagation in EJB to remote EJB calls
The ejb-security-context-propagation
quickstart demonstrates how the security context can be propagated to a remote EJB using a remote outbound connection configuration
The ejb-security-context-propagation
quickstart demonstrates how the security context of an EJB can be propagated to a
remote EJB in WildFly Application Server.
The quickstart makes use of two EJBs, SecuredEJB
and IntermediateEJB
, to verify that the security context propagation is correct, and a RemoteClient
standalone client.
- SecuredEJB
-
The
SecuredEJB
has four methods.String getSecurityInformation(); String guestMethod(); String userMethod(); String adminMethod();
The
getSecurityInformation()
method can be called by all users that are created in this quickstart. The purpose of this method is to return aString
containing the name of thePrincipal
that called the EJB, along with the user’s authorized role information, for example:[Principal=[quickstartUser], In role [guest]=true, In role [user]=true, In role [admin]=false]
The
guestMethod()
,userMethod()
, andadminMethod()`
methods are annotated to require that the calling user is authorized for rolesguest
,user
andadmin
respectively.
- IntermediateEJB
-
The
IntermediateEJB
contains a single method. Its purpose is to make use of a remote connection and invoke each of the methods on theSecuredEJB
. A summary is then returned with the outcome of the calls.
- RemoteClient
-
Finally there is the
RemoteClient
stand-alone client. The client makes calls using the identity of the established connection.In the real world, remote calls between servers in the servers-to-server scenario would truly be remote and separate. For the purpose of this quickstart, we make use of a loopback connection to the same server so we do not need two servers just to run the test.
The application this project produces is designed to be run on WildFly Application Server 35 or later.
All you need to build this project is Java SE 17.0 or later, and Maven 3.6.0 or later. See Configure Maven to Build and Deploy the Quickstarts to make sure you are configured correctly for testing the quickstarts.
In the following instructions, replace WILDFLY_HOME
with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.
When you see the replaceable variable QUICKSTART_HOME, replace it with the path to the root directory of all of the quickstarts.
This quickstart uses the default standalone configuration plus the modifications described here.
It is recommended that you test this approach in a separate and clean environment before you attempt to port the changes in your own environment.
This quickstart uses secured management interfaces and requires that you create the following application user to access the running application.
UserName | Realm | Password | Roles |
---|---|---|---|
quickstartUser |
ApplicationRealm |
quickstartPwd1! |
guest,user |
quickstartAdmin |
ManagementRealm |
adminPwd1! |
guest,user,admin |
To add the application user, open a terminal and type the following command:
$ WILDFLY_HOME/bin/add-user.sh -a -u 'quickstartUser' -p 'quickstartPwd1!' -g 'guest,user'
$ WILDFLY_HOME/bin/add-user.sh -a -u 'quickstartAdmin' -p 'adminPwd1!' -g 'guest,user,admin'
Note
|
For Windows, use the WILDFLY_HOME\bin\add-user.bat script.
|
Before you begin, back up your server configuration file.
-
If it is running, stop the WildFly server.
-
Back up the
WILDFLY_HOME/standalone/configuration/standalone.xml
file.
After you have completed testing this quickstart, you can replace this file to restore the server to its original configuration.
-
Open a terminal and navigate to the root of the WildFly directory.
-
Start the WildFly server with the default profile by typing the following command.
$ WILDFLY_HOME/bin/standalone.sh
NoteFor Windows, use the WILDFLY_HOME\bin\standalone.bat
script.
You configure the security domain by running JBoss CLI commands. For your convenience, this quickstart batches the commands into a configure-elytron.cli
script provided in the root directory of this quickstart.
-
Before you begin, make sure you do the following:
-
Back up the WildFly standalone server configuration as described above.
-
Start the WildFly server with the standalone default profile as described above.
-
-
Review the
configure-elytron.cli
file in the root of this quickstart directory. This script adds the configuration that enables security for the quickstart deployment. Comments in the script describe the purpose of each block of commands. -
Open a new terminal, navigate to the root directory of this quickstart, and run the following command, replacing
WILDFLY_HOME
with the path to your server:$ WILDFLY_HOME/bin/jboss-cli.sh --connect --file=configure-elytron.cli
NoteFor Windows, use the WILDFLY_HOME\bin\jboss-cli.bat
script. -
Because this example quickstart demonstrates security, system exceptions are thrown when secured EJB access is attempted by an invalid user. If you want to review the security exceptions in the server log, you can skip this step. If you want to suppress these exceptions in the server log, run the following command, replacing
WILDFLY_HOME
with the path to your server:$ WILDFLY_HOME/bin/jboss-cli.sh --connect --file=configure-system-exception.cli
NoteFor Windows,use the WILDFLY_HOME\bin\jboss-cli.bat
script.You should see the following result when you run the script:
The batch executed successfully
-
Stop the WildFly server.
After stopping the server, open the WILDFLY_HOME/standalone/configuration/standalone.xml
file and review the changes.
-
The following
application-security-domain
was added to theejb3
subsystem:<application-security-domains> <application-security-domain name="quickstart-domain" security-domain="ApplicationDomain"/> </application-security-domains>
The
application-security-domain
enables security for the quickstart EJBs. It maps thequickstart-domain
security domain that is set in the EJBs using the Java annotation@SecurityDomain("quickstart-domain")
to the ElytronApplicationDomain
that is responsible for authenticating and authorizing access to the EJBs. -
The following
ejb-outbound-configuration
authentication configuration andejb-outbound-context
authentication context were added to theelytron
subsystem:<authentication-configuration name="ejb-outbound-configuration" security-domain="ApplicationDomain" sasl-mechanism-selector="PLAIN"/> <authentication-context name="ejb-outbound-context"> <match-rule authentication-configuration="ejb-outbound-configuration"/> </authentication-context>
The
ejb-outbound-configuration
contains the authentication configuration that will be used when invoking a method on a remote EJB, for example whenIntermediateEJB
calls the methods on theSecuredEJB
. The above configuration specifies that the identity that is currently authenticated to theApplicationDomain
will be used to establish the connection to the remote EJB. Thesasl-mechanism-selector
defines the SASL mechanisms that should be tried. In this quickstart thePLAIN
mechanism has been chosen because other challenge-response mechanisms such asDIGEST-MD5
can’t provide the original credential to establish the connection to the remote EJB.The
ejb-outbound-context
is the authentication context that is used by the remote outbound connection and it automatically selects theejb-outbound-configuration
. -
The following
ejb-outbound
outbound-socket-binding connection was created within thestandard-sockets
socket-binding-group:<outbound-socket-binding name="ejb-outbound"> <remote-destination host="localhost" port="8080"/> </outbound-socket-binding>
For the purpose of the quickstart we just need an outbound connection that loops back to the same server. This will be sufficient to demonstrate the server-to-server capabilities.
-
The following
ejb-outbound-connection
remote-outbound-connection was added to the outbound-connections within theremoting
subsytem:<outbound-connections> <remote-outbound-connection name="ejb-outbound-connection" outbound-socket-binding-ref="ejb-outbound" authentication-context="ejb-outbound-context"/> </outbound-connections>
-
Finally, the
application-sasl-authentication
factory was updated in theelytron
subsystem to include thePLAIN
mechanism:<sasl-authentication-factory name="application-sasl-authentication" sasl-server-factory="configured" security-domain="ApplicationDomain"> <mechanism-configuration> <mechanism mechanism-name="PLAIN"/> <mechanism mechanism-name="JBOSS-LOCAL-USER" realm-mapper="local"/> <mechanism mechanism-name="DIGEST-MD5"> <mechanism-realm realm-name="ApplicationRealm"/> </mechanism> </mechanism-configuration> </sasl-authentication-factory>
Note that the
http-connector
in theremoting
subsystem uses thisapplication-sasl-authentication
authentication factory. It allows for the identity that was established in the connection authentication to be propagated to the components. -
If you ran the script to suppress system exceptions, you should see the following configuration in the
ejb3
subsystem.<log-system-exceptions value="false"/>
-
Make sure WildFly server is started.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type the following command to build the quickstart.
$ mvn clean install
-
Type the following command to deploy the quickstart.
$ mvn wildfly:deploy
This deploys the ejb-security-context-propagation/target/ejb-security-context-propagation.jar
to the running instance of the server.
You should see a message in the server log indicating that the archive deployed successfully.
This quickstart includes integration tests, which are located under the src/test/
directory. The integration tests verify that the quickstart runs correctly when deployed on the server.
Follow these steps to run the integration tests.
-
Make sure WildFly server is started.
-
Make sure the quickstart is deployed.
-
Type the following command to run the
verify
goal with theintegration-testing
profile activated.$ mvn verify -Pintegration-testing
When you run the integration tests, you see the following output. Note there may be other log messages interspersed between these.
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * IntermediateEJB - Begin Testing with principal quickstartUser * *
Remote Security Information: [Principal=[quickstartUser], In role [guest]=true, In role [user]=true, In role [admin]=false]
Can invoke guestMethod? true
Can invoke userMethod? true
Can invoke adminMethod? false
* * IntermediateEJB - End Testing * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Can invoke userMethod? true
Can invoke adminMethod? true
* * IntermediateEJB - End Testing * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
As can be seen from the output the identities authenticated to the intermediate EJB were propagated all the way to the remote secured EJB and their roles have been correctly evaluated.
If you did not run the script to suppress system exceptions, you should see the following exceptions in the WildFly server console or log. The exceptions are logged for each of the tests where a request is rejected because the user is not authorized.

When you are finished testing the quickstart, follow these steps to undeploy the archive.
-
Make sure WildFly server is started.
-
Open a terminal and navigate to the root directory of this quickstart.
-
Type this command to undeploy the archive:
$ mvn wildfly:undeploy
You can restore the original server configuration using either of the following methods.
-
You can run the
restore-configuration.cli
script provided in the root directory of this quickstart. -
You can manually restore the configuration using the backup copy of the configuration file.
-
Start the WildFly server as described above.
-
Open a new terminal, navigate to the root directory of this quickstart, and run the following command, replacing
WILDFLY_HOME
with the path to your server:$ WILDFLY_HOME/bin/jboss-cli.sh --connect --file=restore-configuration.cli
NoteFor Windows, use the WILDFLY_HOME\bin\jboss-cli.bat
script.
This script reverts the changes made to the ejb3
, elytron
and remoting
subsystems. You should see the following result when you run the script.
The batch executed successfully
process-state: reload-required
Note
|
If you ran the script to suppress system exceptions, you need to restore the logging of system exceptions. Run the above command, passing
|
When you have completed testing the quickstart, you can restore the original server configuration by manually restoring the backup copy the configuration file.
-
If it is running, stop the WildFly server.
-
Replace the
WILDFLY_HOME/standalone/configuration/standalone.xml
file with the backup copy of the file.
Instead of using a standard WildFly server distribution, you can alternatively provision a WildFly server to deploy and run the quickstart. The functionality is provided by the WildFly Maven Plugin, and you may find its configuration in the quickstart pom.xml
:
<profile>
<id>provisioned-server</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.wildfly.plugins</groupId>
<artifactId>wildfly-maven-plugin</artifactId>
<configuration>
<discover-provisioning-info>
<version>${version.server}</version>
</discover-provisioning-info>
<add-ons>...</add-ons>
</configuration>
<executions>
<execution>
<goals>
<goal>package</goal>
</goals>
</execution>
</executions>
</plugin>
...
</plugins>
</build>
</profile>
When built, the provisioned WildFly server can be found in the target/server
directory, and its usage is similar to a standard server distribution, with the simplification that there is never the need to specify the server configuration to be started.
Follow these steps to run the quickstart using the provisioned server.
-
Make sure the server is provisioned.
$ mvn clean install
-
Add the quickstart user:
$ target/server/bin/add-user.sh -a -u 'quickstartUser' -p 'quickstartPwd1!' -g 'guest,user'
-
Add the quickstart admin:
$ target/server/bin/add-user.sh -a -u 'quickstartAdmin' -p 'adminPwd1!' -g 'guest,user,admin'
For Windows, use the WILDFLY_HOME\bin\add-user.bat
script.
-
Start the WildFly provisioned server, using the WildFly Maven Plugin
start
goal.$ mvn wildfly:start
-
Type the following command to run the integration tests.
$ mvn verify -Pintegration-testing
-
Shut down the WildFly provisioned server.
$ mvn wildfly:shutdown
