[rules-users] Authorisation of Guvnor users on Glassfish

[Chris Selwyn]

To answer my own question (and record a method that works for posterity)...

What I did was:-

    * Configure my Glassfish domain's login.conf with a "seam"
      LoginModule as follows
      seam {
           org.jboss.seam.security.jaas.SeamLoginModule required;
      };

    * Create a Seam authenticator that authenticates against a Glassfish
      realm using Glassfish's ProgrammaticLogin as shown below.
      The code in the authenticator uses the hardcoded realm called
      "fileRealm". Maybe I need to find a way to configure that.

    * Configure my Guvnor's identity component by changing the
      components.xml inside the exploded drools-guvnor directory as
      follows:-
      <security:identity
      authenticate-method="#{gfauthenticator.authenticate}"
      jaas-config-name="seam"/>
      This ties the inbuilt Seam JAAS LoginModule to the Glassfish realm
      authenticator.

    * Add new users to the "file" realm.

    * Now the users in the file realm can be authenticated as Guvnor users.

             return plogin.login(userNm, pass, "fileRealm", true);
