  • How to Set Up SSO Between IBM WebSphere and SAP EP Using JAAS

    Hi
    I have read the article on SDN called "How to Set Up SSO Between IBM WebSphere and SAP EP Using JAAS", which is also the name of my posting.
    The reason why I post this is that I've tried to follow the links in the PDF to get the file WebsphereEpSsoLib.zip but I get an error 403, which tells me that the file is not there.
    Does anybody know where this file went or can somebody tell me an alternative place to get this file?
    Jacob

    Please open the associated whitepaper, and you can find the download link to the .ZIP file on page 4.
    https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/ibm/how to set up single sign-on between an ibm websphere portal and the sap enterprise portal using jaas.pdf
    Hope that works!

  • Has anyone used JAAS with WebLogic?

    Has anyone used JAAS with Weblogic? I was looking at their example, and I have a bunch of questions about it. Here goes:
    Basically the problem is this: the plug-in LoginModule model of JAAS used in WebLogic (with EJB Servers) seems to allow clients to falsely authenticate.
    Let me give you a little background on what brought me to this. You can find the WebLogic JAAS example (to which I refer below) in the pdf: http://e-docs.bea.com/wls/docs61/pdf/security.pdf . (I believe you want pages 64-74) WebLogic, I believe goes about this all wrong. They allow the client to use their own LoginModules, as well as CallBackHandlers. This is dangerous, as it allows them to get a reference (in the module) to the LoginContext's Subject and authenticate themselves (i.e. associate a Principal with the subject). As we know from JAAS, the way AccessController checks permissions is by looking at the Principal in the Subject and seeing if that Principal is granted the permission in the "policy" file (or by checking with the Policy class). What it does NOT do, is see if that Subject
    has the right to hold that Principal. Rather, it assumes the Subject is authenticated.
    So a user who is allowed to use their own Module (as WebLogic's example shows) could do something like:
    //THEIR LOGIN MODULE (SOME CODE CUT-OUT FOR BREVITY)
    public class BasicModule implements LoginModule
    private NameCallback strName;
    private PasswordCallback strPass;
    private CallbackHandler myCB;
    private Subject subj;
             //INITIALIZE THIS MODULE
               public void initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options)
                      try
                           //SET SUBJECT
                             subj = subject;  //NOTE: THIS GIVES YOU REFERENCE
    TO LOGIN CONTEXT'S SUBJECT
                                                     // AND ALLOWS YOU TO PASS
    IT BACK TO THE LOGIN CONTEXT
                           //SET CALLBACKHANDLERS
                             strName = new NameCallback("Your Name: ");
                             strPass = new PasswordCallback("Password:", false);
                             Callback[] cb = { strName, strPass };
                           //HANDLE THE CALLBACKS
                             callbackHandler.handle(cb);
                      } catch (Exception e) { System.out.println(e); }
         //LOG THE USER IN
           public boolean login() throws LoginException
              //TEST TO SEE IF SUBJECT HOLDS ANYTHING YET
              System.out.println( "PRIOR TO AUTHENTICATION, SUBJECT HOLDS: " +
    subj.getPrincipals().size() + " Principals");
              //SUBJECT AUTHENTICATED - BECAUSE SUBJECT NOW HOLDS THE PRINCIPAL
               MyPrincipal m = new MyPrincipal("Admin");
               subj.getPrincipals().add(m);
               return true;
             public boolean commit() throws LoginException
                   return true;
        }(Sorry for all that code)
    I tested the above code, and it fully associates the Subject (and its principal) with the LoginContext. So my question is, where in the process (and code) can we put the LoginContext and Modules so that a client cannot
    do this? With the above example, there is no Security. (a call to: myLoginContext.getSubject().doAs(...) will work)
    I think the key here is to understand JAAS's plug-in security model to mean:
    (Below are my words)
    The point of JAAS is to allow an application to use different ways of authenticating without changing the application's code, but NOT to allow the user to authenticate however they want.
    In WebLogic's example, they unfortunately seem to have used the latter understanding, i.e. "allow the user to authenticate however they want."
    That, as I think I've shown, is not security. So how do we solve this? We need to put JAAS on the server side (with no direct JAAS client-side), and that includes the LoginModules as well as LoginContext. So for an EJB Server this means that the same internal permission
    checking code can be used regardless of whether a client connects through
    RMI/RMI-IIOP/JEREMIE (etc). It does NOT mean that the client gets to choose
    how they authenticate (except by choosing YOUR set ways).
    Before we even deal with a serialized subject, we need to see how JAAS can
    even be used on the back-end of an RMI (RMI-IIOP/JEREMIE) application.
    I think what needs to be done, is the client needs to have the stubs for our
    LoginModule, LoginContext, CallBackHandler, CallBacks. Then they can put
    their info into those, and everything is handled server-side. So they may
    not even need to send a Subject across anyways (but they may want to as
    well).
    Please let me know if anyone sees this problem too, or if I am just completely
    off track with this one. I think figuring out how to do JAAS as though
    everything were local, and then putting RMI (or whatever) on top is the
    first thing to tackle.

    Oracle supports feedback form metalink was; "What you exactly want to approach is not possible in Htmldb"
    I can guess that it is not
    exactly possible since I looked at the forums and documantation etc. but
    couldnt find anything similar than this link; "http://www.oracle.com/technology/products/database/htmldb/howtos/tabular_form.h
    t". But this is a very common need and I thought that there must be at least a workaround?
    How can I talk or write to Html Db development team about this since any ideas, this is very important item in a critial project?
    I will be able to satisfy the need in a functional way if I could make the
    select lists in the tabular form dynamic with the noz_id;
    SELECT vozellik "Özellik",
    htmldb_item.select_list_from_query(2, t2.nozellik_deger, 'select vdeger
    a,vdeger b from tozellik_deger where noz_id = 10') "Select List",

    FROM vcihaz_grup_ozellik t1, tcihaz_oz t2
    WHERE t1.noz_id = t2.noz_id
    AND t2.ncihaz_id = 191
    AND t1.ngrup_id = 5
    But what I exactly need i something like this dynamic query;
    SELECT
    vozellik "Özellik",
    CASE
    WHEN (t2.nozellik_deger IS NULL AND t2.vcihaz_oz_deger IS NOT NULL) THEN

  • Client remote Authentication using JAAS and EJB Access

    Hi,
    I have a problem using JAAS in combination with Sun One Appserver 8.1 and a java remote client trying to access an EJB. Here is the scenario:
    I have implemented an EJB who's methods are protected through the deployment descriptor:
            <assembly-descriptor>
                 <security-role>
                    <description>role for clients outside of the server </description>
                    <role-name>sedna</role-name>
                  </security-role>
                <method-permission>
                  <role-name>sedna</role-name>
                  <method>
                    <ejb-name>ServerInfoBean</ejb-name>
                    <method-intf>Remote</method-intf>
                    <method-name>*</method-name>
                  </method>
                </method-permission>
                <method-permission>
                  <unchecked/>
                  <method>
                    <ejb-name>ServerInfoBean</ejb-name>
                    <method-name>getVersion</method-name>
                  </method>
                  <method>
                    <ejb-name>ServerInfoBean</ejb-name>
                    <method-name>create</method-name>
                  </method>
                </method-permission>
            </assembly-descriptor>I've deployed the EJB in a jar file which was packed into an ear file of a bigger application. The role has been mapped to the admin Principal in the sun-ejb-jar.xml descriptor.
    I can find the EJB, create it, and call the unchecked method getVersion and that works fine, so far so good.
    But then I try to access another method which is protected and then I get this exception
    org.omg.CORBA.NO_PERMISSION:   vmcid: 0x2000  minor code: 1806 completed: Maybe
            at com.sun.enterprise.iiop.POAProtocolMgr.mapException(POAProtocolMgr.java:179)
            at com.sun.ejb.containers.BaseContainer.postInvoke(BaseContainer.java:853)
            at com.sun.ejb.containers.EJBObjectInvocationHandler.invoke(EJBObjectInvocationHandler.java:137)
    ...I have to mention that I do make a login via the LoginContext. My jaas.config File has a reference to the com.sun.enterprise.security.auth.login.ClientPasswordLoginModule module.
    After login (which works perfectly) I lookup the context with a corbaname url which - if I understood it right - ignores the Context.SECURITY_PRINCIPAL and Context.SECURITY_CREDENTIALS settings.
    After that I make the calls to the EJB. And I am allways ANONYMOUS on the server side, which is definitely the problem. Because ANONYMOUS is not allowed to call the protected EJB Methods. But I made a jaas login in advance. So where am I making a mistake???
    Am I doing something wrong?
    Need help! Thx,
    Stephan

    Hi.
    I understand correctly that you call Subject.doAs on
    the client to call the remote EJB. I guess It isn't
    right way.I had also a bad feeling about this, so I forget it. But anyway it wasn't working with or without using that doAs().
    >
    >
    Subject contextSubject =
    Subject.getSubject(AccessController.getContext());
    contextSubject.getPrincipals();This code throws exceptions in the Appserver. Unfortunately they are catched somewhere so I'm unable to find out what was going wrong. But I guess, that these exceptions where security exceptions. Never the less thanks for the hint!
    But I don't think that doing the check on the server side is the way I want to go because that is programmatically security and I want to use the declarative security which can be used through the deployment descriptor. If used correctly - and supposed I do not completely misunderstand the specification - then it should be possible to create an EJB that is protected via it's deployment descriptor and access it through the client only if the client has been authenticated through JAAS mechanisms. After successful authentication the principal should be accessible through the EJB context but not for security check, that should allready been done at this time.
    Unfortunately I don't find any resource on the internet describing the scenario in such a detail that I can reproduce it. There are only very high level documentations and hints in forums.
    Again, thanks for your effort,
    Stephan

  • Navigation problem when using tiles with JSF

    Hi all,
    I m using tiles with JSF. i have included all the libraries and jsp page is rendered properly. but when i use <h:commandLink> in the body part of the JSP , i cannot go to the specified link. when we use tiles, what changes need to be done in faces-config file?? i mean what navigation rule we need to specify ??

    Hello, I have the same problem; JSF+Tiles = No navigation.
    One basic question is should I reference the parent jsp or the included body jsp in the faces-config.xml file.
    For example: The login.jsp is a main tiles page that includes a menu.jsp, header.jsp & a loginBody.jsp.
    Hence the faces-config could have this rule;
    <navigation-rule>
    <from-view-id>/login.jsp</from-view-id>
    <navigation-case>
    <to-view-id>/catalog.jsp</to-view-id>
    </navigation-case>
    </navigation-rule>
    (I've left the outcome tag out to simplify this post)
    Or, I could refer loginBody.jsp in the navigation rule;
    <navigation-rule>
    <from-view-id>/loginBody.jsp</from-view-id>
    <navigation-case>
    <to-view-id>/catalog.jsp</to-view-id>
    </navigation-case>
    </navigation-rule>
    The loginBody.jsp has a commandbutton which a user clicks which starts the navigation.
    Neither seems to work unfortunately & I'm a stuck.
    Thanks

  • Using JAAS in a BC4J Client

    Hello
    We are building a BC4J application.
    We would like to use JAAS on the client side (Swing Client), to do some authorization.
    I made a test, authentication a user trough JAAS on the client as follow:
    // Auhorization
    CallbackHandler handler = new InfoCallbackHandler();
    String s = "oracle.security.jazn.tools.Admintool";
    LoginContext loginContext = new LoginContext(s, handler);
    loginContext.login();
    Subject subject = loginContext.getSubject();
    // authenticated action
    Subject.doAs(subject, this);
    This works, as long as the client has access to the jazn.xml file.
    As far as I understand, this loads the RealmLoginModule.
    The RealmLoginModule uses either a jazn.xml file, or LDAP for authentication.
    Now I'm curios about where the RealmLoginModule gets its information from, when the client is running on an other machine than the OC4J Server.
    Where does the RealmLoginModule get the connection information for the OC4J or LDAP- server from?
    Do I have to deliver the security information (jazn.xml file) to the client (I dont want to expose all this information to the Hackers on the client side)?
    Is there a way to delegate the JAAS calls to the middle tier (a security provider , LoginModule, that does RMI-calls to an EJB-component)?
    Is there a way to do authorization with the BC4J interfaces on the client (something like boolean ApplikacitonModule.isUserInRole(Role) or javax.security.auth.Subject ApplikacitonModule.getSubject() or java.util.Set ApplikacitonModule.getPrincipalsForSubject())?
    I would like to get a javax.security.auth.Subject representing the user (and password)
    that is authenticated in the middle tier. This is the Subject (defined by username & password)),
    used for the JNDI lookup, and by the whole J2EE (EJB) security, when creating a root ApplicationModule.
    Is this possible?
    Regards
    Matthais Gerber

    Hi,
    In JDeveloper 9.0.3, BC4J has JAAS support in the middle-tier. You could set jbo.security.enforce to "Test" or "Must" on the application module using "Configuration...", "Edit" in JDev. If you are using the default Oracle 9iAS JAAS you will also need to include BC4J Security library in the project. The jdk\jre\lib\securtiy\java.security should have login.configuration.provider=oracle.security.jazn.spi.LoginConfigProvider.
    You do not need to create LoginContext, CallbackHandler, etc. in either your client app or business objects.
    If you are not using OC4J, you need to have another loginmodule that implement javax.security.auth.spi.LoginModule. You need to set the jbo.security.loginmodule with you loginmodule name, include the class or jar in your library, specify the jaas config file on the java runtime option.
    Please refer to 9.0.3 online help "Working with Security in BC4J" for more information.
    Thanks,
    Yvonn

  • Using JAAS without config text files

    Hi everybody,
    I'm trying to develop an application using JAAS for authentication and authorization, but I don't want to depend on the text files for configuration.
    This application is going to be distributed using Webstart, so I don't know which configuration the user will have.
    Is there anyway to bypass these files?
    Thanks a lot,
    Luis Javier

    For the LoginModule part, you could try to set your own Configuration object.
    Ses javax.security.auth.login.Configuration.setConfiguration
    You should be able to inherit from Configuration and provide your own method to
    provide AppConfigEntries.

  • Using expressions in jsf tags

    I have a problem with using expressions in jsf tags! I know this
    topic was discussed before but it doesn`t work.
    I want to use the following jsf-code:
    <h:panel_data id="tab" var="vari" modelReference="Bean.varis">
    <h:output_text id="Id" modelReference="vari.id"/>
    <h:command_hyperlink id="hyper" href="next.jsp" label="Detail">
    <f:parameter id="Param1" name="id" value="vari.id"/>
    </h:command_hyperlink>
    </h:panel_data>
    The value of the parameter should have the value of vari.id!! Why doesn`t it work?? I also tried to use value="${vari.id}" and value=<%= vari.id %>.
    I have also changed the jsf_core.tld from
         <rtexprvalue>false</rtexprvalue>
    to
         <rtexprvalue>true</rtexprvalue>
    Does anybody know what to do? Where should the .tld-files be localized when i deploy the webapplication??

    If you want your parameter's value to be pulled from the model, you must
    use modelReference instead of value. Try that and see if it works.

  • Using Frames in JSF

    Can anyone provide an example on how to use frames inside JSF? I don't know how to define the framesets inside the jsf file. A simple example will go a long way. Thanks.

    Nope, I'm not big on samples, especially of code I've never tried to write. Give it a try, if you have a problem post your code and we'll take a look.

  • Using EL in JSF

    Hello,
    maybe a stupid question but I asked myself why I can't use the $ symbol when using EL in JSF. Can somebody tell me the difference between using # or $ when writing EL in JSP/JSF
    Thx
    Chris

    Yes, it very depends.
    JSF 1.1 and JSP2.0 have their own EL. They do not understand each other.
    #{} uses only for jsf tag attributes. You cannot able to use it outside (Except with Facelets, but it is not about JSP at all).
    In contrast, ${} cannot be used inside the JSF tag attributes.
    JSF1.2 and JSP2.1 use unified EL. Now, you can use them both everywhere on the page, but the major difference still exists.
    ${} is a immediate EL
    #{} is a deferral EL
    #{} orginizes binding instead of immediate replacement. You can use #{} as an L-Value expression.
    For more information read this article:
    http://today.java.net/pub/a/today/2006/03/07/unified-jsp-jsf-expression-language.html
