java.lang.ClassNotFoundException: org.jboss.security.negotiation.NegotiationAuthenticator

Question

While deploying webapp on JBOSS EAP 6.1, I am receiving following error:

Caused by: java.lang.ClassNotFoundException: org.jboss.security.negotiation.NegotiationAuthenticator from [Module "deployment.dummy.ear.dummy-web.war:main" from Service Module Loader]

We are using SPNEGO authentication and jboss-web.xml is configured as:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <context-root>dummy</context-root>
    <security-domain>SPNEGO</security-domain>
    <valve>
        <class-name>org.jboss.security.negotiation.NegotiationAuthenticator</class-name>
    </valve>
    <jacc-star-role-allow>true</jacc-star-role-allow>
</jboss-web>

I found reference to similar question on RedHat portal. But its unanswered. Can you please tell me how to resolve this issue? Please let me know, if you require more information.

Thanks.

Add in WEB-INF/jboss-deployment-structure.xml the next dependency:

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.jboss.security.negotiation" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>
