Description of problem:
Build 27 of the ER7 installer incorrectly configures the standalone.xml file with respect to the overlord-jaxrs login module.  

The current markup is this:

<security-domain name="overlord-jaxrs" cache-type="default">
   <authentication>
      <login-module code="org.overlord.commons.auth.jboss7.SAMLBearerTokenLoginModule" flag="sufficient">
         <module-option name="allowedIssuers" value="/s-ramp-ui,/dtgov,/dtgov-ui,/gadget-web,/bpel-console"/>
         <module-option name="signatureRequired" value="true"/>
         <module-option name="keystorePath" value="${jboss.server.config.dir}/overlord-saml.keystore"/>
         <module-option name="keystorePassword" value="VAULT::vault::saml-keystore.password::1"/>
         <module-option name="keyAlias" value="overlord"/>
         <module-option name="keyPassword" value="VAULT::overlord::overlord-alias.password::1"/>
      </login-module>
      <login-module code="RealmDirect" flag="required">
          <module-option name="password-stacking" value="useFirstPass"/>
      </login-module>
   </authentication>
 </security-domain>

The values for "keystorePassword" and "keyPassword" are missing the surrounding ${}.  So they *should* be:

         <module-option name="keystorePassword" value="${VAULT::vault::saml-keystore.password::1}"/>
         <module-option name="keyPassword" value="${VAULT::overlord::overlord-alias.password::1}"/>
