jboss EAP 6.3.3 fallback authentication

Question

I have an app to deploy that requires SSO to work off AD. This is working with the following snippets:

jboss-web.xml

<security-domain>java:/jaas/SPNEGO</security-domain>
<valve>
  <class-name>org.jboss.security.negotiation.NegotiationAuthenticator</class-name>
</valve>

jboss-deployment-structure.xml

<dependencies>
  <module name="javax.api" slot="main"/>
  <module name="org.jboss.security.negotiation" />
  <module name="sun.jdk" slot="main"/>
</dependencies>

domain.xml

<subsystem xmlns="urn:jboss:domain:security:1.2">

    <security-domain name="other" cache-type="default">
      <authentication>

        </login-module>
      </authentication>
    </security-domain>
  </security-domains>
</subsystem>

I would like to deploy the same app to another server with a different profile without changing the jboss-web.xml and jboss-deployment-structure.xml to have a fallback authentication to use the databaseserverlogin module. This app will then be used by others to make RPC calls to it (no SSO). I tried stacking the login-module below:

<login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required">
  <module-option name="dsJndiName" value="java:/MyDatabaseDS"/>
  <module-option name="principalsQuery" value="select passwd from Users where username=?"/>
  <module-option name="rolesQuery" value="select userRoles, 'Roles' from UserRoles where username=?"/>
  <module-option name="ignorePasswordCase" value="true"/>
</login-module>

The error I'm getting running a wget command (in hoping that it will fallback to databaseserverlogin module)

HTTP request sent, awaiting response... 401 Unauthorized
Unknown authentication scheme.
Authorization failed.

I can successfully use the databaseserverlogin module by itself, but not without stripping out the valve entry in jboss-web.xml.

Is this setup possible? I'm trying to avoid modifying the WAR file received from development.

I tried the following link but stuck on class not found org.jboss.security.negotiation.NegotiationWithBasicFallbackAuthenticator? I assumed the patch would have been included in latest jboss EAP 6.3.3? Probably a bad assumption.

Thanks in advance for any guidance (and patience if I'm not making sense).

Sorted, with help from RedHat Support.

•To enable fallback to basic, add the following to the top of the WEB-INF/web.xml file:

<context-param>
  <description>BASIC Authentication FallBack</description>
  <param-name>org.jboss.security.negotiation.NegotiationAuthenticator.BasicAuthFallBack</param-name>
  <param-value>true</param-value>
</context-param>
