If a customized portal container was used in JBoss Enterprise Portal Platform 5.1, its login module list should be adapted. The following would need to be added on top of the other login module definitions in the file gatein-jboss-beans.xml:

If this is not done, it will not be possible to log into the portal.

      <login-module code="org.gatein.wci.security.WCILoginModule" flag="optional">
        <module-option name="portalContainerName">ecmdemo</module-option>
        <module-option name="realmName">gatein-domain-ecmdemo</module-option>
      </login-module>
