Re: Security Realm Error

Hi,

You was right, I had an error in my user mapping. (Thanks Aaron)

But now ....
The user login is ok, but when I execute HttpServletRequest.isUserInRole("IBMS") in my code, it return false.
I debugged my code ...
HttpServletRequest -- userPrincipal is present with the correct name and subjects but roles is null.

Any directions?

 Thanks,

I think that UnsupportedCallbackException is kind of expected.  If I
remember right, we call the login module once just to establish what
callbacks it wants, and we call it a second time to do the actual
login.  So the fact that it gets called once and an exception is
thrown should be OK, just don't do anything hasty.  When it gets
called the second time the login should work.

Now, looking back at your web app plan, I see this:

    <security>
        <default-principal>
            <principal name="anonymous"
            class="com.ias.ibms.auth.IBMSRole"
            />
        </default-principal>
    </security>

That doesn't actually map any user to any J2EE roles.  In other words,
no logins are treated as members of the IBMS J2EE role, so even if the
login to the web app is valid, the user probably gets an access denied
error.  To fix, that, you need to list the login module principals
that should be members of the J2EE role named IBMS, like this:

    <security>
        <default-principal>
            <principal name="anonymous"
            class="com.ias.ibms.auth.IBMSRole"
            />
        </default-principal>
        <role-mapping>
          <role role-name="IBMS">
            <principal name="some-principal-name"
            class="com.ias.ibms.auth.IBMSRole"
            />
          </role>
        </role-mapping>
        </role>
    </security>

So the combination of the principal class (com...IBMSRole) and
principal name (some-principal-name) should uniquely identify a
principal returned by the login module.  (e.g. some modules return
both user principals and group principals and a particular login may
get some of both, and there could be users and groups with the same
name like 'administrator').  You can list more than one role in the
role-mapping section and more than one principal in each role section
if you want to do more extensive mapping (e.g. 2 users and 3 groups
should all count as members of the "IBMS" role).

For more details, you can look at:

http://chariotsolutions.com/geronimo/web-plan.html#web-plan-security

Particularly example 11.5.

 Hi,

 I'm still having trouble deploying the security realm. The realm itself is
now deployed, but when trying to authenticate a user at the webapp I'm
getting an UnsupportedCallbackException.

 Actually I'm tracing it and it calls the LoginModule's login() method
twice. The first time it throws the exception but the second one it does
pass back the username and password through the callbacks.

 The module and the webapp are working fine inside a stand-alone Tomcat. Any
directions?

 Thanks,

 Thanks Vamsavardhana!

 It's running fine.

 But I had trying to deploy the security realm configuration plan by command
line and it did not run. Now I deploy the security realm configuration plan
by web console.

 Thanks

Hi Yeray,

 The dependency you have included in geronimo-web.xml needs to go into this
security realm configuration plan.  You do not need that dependency tag in
geronimo-web.xml

 Uninstall the configuration "SecurityRealm-ibms" from application
management portlets.  Create a security realm plan xml separately.  You can
simply add the dependency tag to the security realm plan you have sent
earlier and deploy this newly created plan.

Yeray,

Can you copy paste the plan for the security realm.  To see the plan,

access the Security Realms portlet in Admin Console, Click on "edit" for the
realm and click on "Show plan" button in the next page.

Hi,

I´m trying to deploy a War in Geronimo with my own Security Realm.

First, I add an entry in Common libraries (the jar containing my

classes)

Next, I add a security realm.

And finally, I deploy my a web app with the following deployment plan:

----------------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8"?>

        <uri>ibms/ibmsauth/0.9.1/jar</uri>
    </dependency>

    <context-root>/ibms</context-root>

    <security-realm-name>ibms</security-realm-name>

            <principal name="anonymous"

            />
        </default-principal>
    </security>
</web-app>

The deploy is correct but when I try to access to my application ,

occurs the following exception:
