Configure the Full Distribution for JBoss EAP/WildFly

This page explains how to configure the full distribution for the JBoss EAP/WildFly application server.

LDAP

In order to setup LDAP for the JBoss EAP/WildFly Application Server distribution, you have to perform the following steps:

Adjust the Process Engine Configuration

Edit the file standalone.xml (or domain.xml) provided by the JBoss EAP/WildFly Application Server and add the LDAP Identity Provider Plugin and the Administrator Authorization Plugin.

<subsystem xmlns="urn:org.camunda.bpm.jboss:1.1">
  <process-engines>
    <process-engine name="default" default="true"> ...
      <properties>...</properties>
      <plugins>
        <plugin>
          <class>org.camunda.bpm.identity.impl.ldap.plugin.LdapIdentityProviderPlugin</class>
          <properties>

            <property name="serverUrl">ldap://localhost:4334/</property>
            <property name="managerDn">uid=jonny,ou=office-berlin,o=camunda,c=org</property>
            <property name="managerPassword">s3cr3t</property>

            <property name="baseDn">o=camunda,c=org</property>

            <property name="userSearchBase">ou=employees</property>
            <property name="userSearchFilter">(objectclass=person)</property>

            <property name="userIdAttribute">uid</property>
            <property name="userFirstnameAttribute">cn</property>
            <property name="userLastnameAttribute">sn</property>
            <property name="userEmailAttribute">mail</property>
            <property name="userPasswordAttribute">userpassword</property>

            <property name="groupSearchBase">ou=roles</property>
            <property name="groupSearchFilter">(objectclass=groupOfNames)</property>
            <property name="groupIdAttribute">ou</property>
            <property name="groupNameAttribute">cn</property>

            <property name="groupMemberAttribute">member</property>

          </properties>
        </plugin>
        <plugin>
          <class>org.camunda.bpm.engine.impl.plugin.AdministratorAuthorizationPlugin</class>
          <properties>
            <property name="administratorUserName">admin</property>
          </properties>
        </plugin>
      </plugins>
    </process-engine>
  </process-engines> ...
</subsystem>

The administratorUserName property should contain the user id of the LDAP user you want to grant administrator authorizations to. You can then use this user to log in to the web application and grant authorizations to additional users.

See our user guide for complete documentation on the LDAP Identity Provider Plugin and the Administrator Authorization Plugin.

HAL Resource Caching

If you use LDAP as Identity Provider, you should consider activating caching of Users and Groups in the Camunda 7 web application. In order to activate this, add the following configuration to the web.xml file of the Camunda 7 web application (camunda-webapp-wildfly-$PLATFORM_VERSION.war/WEB-INF/lib or camunda-webapp-jboss-$PLATFORM_VERSION.war/WEB-INF/lib):

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

  <!-- ... -->

  <listener>
    <listener-class>org.camunda.bpm.engine.rest.hal.cache.HalRelationCacheBootstrap</listener-class>
  </listener>

  <context-param>
    <param-name>org.camunda.bpm.engine.rest.hal.cache.config</param-name>
    <param-value>
      {
        "cacheImplementation": "org.camunda.bpm.engine.rest.hal.cache.DefaultHalResourceCache",
        "caches": {
          "org.camunda.bpm.engine.rest.hal.user.HalUser": {
            "capacity": 100,
            "secondsToLive": 900
          },
          "org.camunda.bpm.engine.rest.hal.group.HalGroup": {
            "capacity": 100,
            "secondsToLive": 900
          }
        }
      }
    </param-value>
  </context-param>

  <!-- ... -->

</web-app>

Add Custom Engine Plugins

  1. Add an additional engine plugin as a module to the folder $WILDFLY_HOME/modules/

  2. Add the module dependency to the file $WILDFLY_HOME/modules/org/camunda/bpm/camunda-engine-plugins/main/module.xml and set the attribute export="true" to make sure that the module is visible in the classpath of Camunda’s subsystem

    <module xmlns="urn:jboss:module:1.0"
        name="org.camunda.bpm.camunda-engine-plugins">
  <dependencies>
    <!-- ... -->
    <module name="org.camunda.bpm.camunda-custom-engine-plugin" export="true" />
  </dependencies>
</module>

    The module.xml file is included in the Camunda 7 distribution. If you install Camunda 7 on a vanilla WildFly container, this file needs to be created manually.

  3. Configure the process engine plugin in the standalone.xml/domain.xml configuration file

The deployment descriptor of the Web applications needs to be adjusted to configure the Session Cookie.

You can find it under WEB-INF/web.xml. Please watch out for the following section:

...
<session-config>
  <cookie-config>
    <secure>false</secure>
    <http-only>true</http-only>
  </cookie-config>
</session-config>
...

Please note that security-related configurations for the Session Cookie can only be applied with the Deployment Descriptor (web.xml) version set to 3.0.

To adjust the SameSite flag of the session cookie, you can configure a SameSiteCookieHandler as described in related the WildFly documentation. This can be used with WildFly versions >= 19.1.0.

To customize the configuration of security-related HTTP headers in the web applications its deployment descriptor needs to be adjusted. You can find it under WEB-INF/web.xml.

Please watch out for the following section:

...
<filter>
  <filter-name>HttpHeaderSecurity</filter-name>
  <filter-class>
    org.camunda.bpm.webapp.impl.security.filter.headersec.HttpHeaderSecurityFilter
  </filter-class>
</filter>

<filter-mapping>
  <filter-name>HttpHeaderSecurity</filter-name>
  <url-pattern>/*</url-pattern>
  <dispatcher>REQUEST</dispatcher>
</filter-mapping>
...

You can change the default behavior by adding configuration parameters to the servlet filter configuration:

...
<filter>
  <filter-name>HttpHeaderSecurity</filter-name>
  <filter-class>
    org.camunda.bpm.webapp.impl.security.filter.headersec.HttpHeaderSecurityFilter
  </filter-class>
  
  <init-param>
    <param-name>contentSecurityPolicyValue</param-name>
    <param-value>
      base-uri 'self';
      default-src 'self' 'unsafe-inline'
    </param-value>
  </init-param>
  
</filter>
...

Please also see the detailed overview about the HTTP Header Security configuration settings.
