    Code Block
    <security:http>
      <security:session-management>
        <security:concurrency-control max-sessions="1"

...

  1.  error-if-maximum-exceeded="true"

...

  1.  expired-url="/web/login"

...

  1.  session-registry-ref="clusterSessionRegistry"/>
      </security:session-management>
    </security:http>
    <bean id="clusterSessionRegistry"

...

  1.  class="org.joget.session.service.ClusterSessionRegistryImpl"></bean>
  2. Uncomment the following in "[tomcat directory]/webapps/jw/WEB-INF/web.xml".

    Code Block
    <!-- Uncomment this listener to support concurrent session control>
    <listener>
          <listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
    </listener>
    <-->
  3. Please modify the following from 'error-if-maximum-exceeded="true"' to ' error-if-maximum-exceeded="false"'.

    Code Block
    <security:session-management>
        <security:concurrency-control max-sessions="1" error-if-maximum-exceeded="false" expired-url="/web/login" session-registry-ref="clusterSessionRegistry"/>
    </security:session-management>

    If you run into any errors, other users have had success by removing the piece of code below:

    Code Block
    session-registry-ref="clusterSessionRegistry"

    This implementation will create a new table in the database named "cluster_session". Note that this implementation is out of our official product support scope.
