RE: Again SecurityFilter integration with JBoss

Hi, thank you very much for you ready answer!!
Looking for a solution I found the Jboss class
org.jboss.web.tomcat.security.JBossSecurityMgrRealm, which has the
following authenticate method:
What i noted here is the following line:

            AuthenticationManager securityMgr =3D =
(AuthenticationManager)
securityCtx.lookup("securityMgr");

It seems much close to yours, but you cast the same context lookup to a
SubjectSecurityanager... I'm not very skilled on those topics, but I
will make a try ...=20

Thank you very much!!
Renato




public Principal authenticate(String username, String credentials)
    {
       boolean trace =3D log.isTraceEnabled();
       if( trace )
          log.trace("Begin authenticate, username=3D"+username);
        SimplePrincipal principal =3D null;
        Context securityCtx =3D getSecurityContext();
        if( securityCtx =3D=3D null )
        {
            return null;
        }

       Principal caller =3D (Principal)
SecurityAssociationValve.userPrincipal.get();
       if( caller =3D=3D null && username =3D=3D null && credentials =
=3D=3D null )
         return null;

        try
        {
            // Get the JBoss security manager from the ENC context
            AuthenticationManager securityMgr =3D =
(AuthenticationManager)
securityCtx.lookup("securityMgr");
            principal =3D new SimplePrincipal(username);
            char[] passwordChars =3D null;
            if( credentials !=3D null )
               passwordChars =3D credentials.toCharArray();
            if( securityMgr.isValid(principal, passwordChars) )
            {
                log.trace("User: "+username+" is authenticated");
                SecurityAssociation.setPrincipal(principal);
                SecurityAssociation.setCredential(passwordChars);
            }
            else
            {
                principal =3D null;
                log.trace("User: "+username+" is NOT authenticated");
            }
        }
        catch(NamingException e)
        {
            principal =3D null;
            log.error("Error during authenticate", e);
        }
       if( trace )
          log.trace("End authenticate, principal=3D"+principal);
        return principal;
    }

Subject: Re: Again SecurityFilter integration with JBoss


Hi,

No problems emailing me - I just sometimes miss personally directed
emails amongst the 200 emails I get a day! Anyway...

Right, yep I've heard of some issues with that version of JBoss - more
specifically it appears to be the Tomcat...

Lately, I'm afraid I have been working on JBoss 4 and I do have it all
working in that, but in order to do so I've had to use JBoss Aspects...
Not ideal but I needed to add a tiny bit of functionality into
securityfilter. So instead of playing with the securityfilter code
directly I used aspects.

Anyway, it looks like I will need a JBoss 3 version in the very near
future (2 weeks) so over the next couple of weeks I'll be sorting out
how to do it on JBoss 3. The problem will need source-level changes to
securityfilter though... :-(

Now maybe I can persuade the securityfilter team to make a tiny change
to the design of one class and add small configuration option... ?


Regards,


Sean
