Potential JavaSSO and Custom Login Module Bugs In Clustered Environment
We've been working with the custom login modules and JavaSSO and have found issues with deployment on 10.1.3.2 in a clustered environment. Deployment on a single server looks like it is working properly.
I'm wondering whether any one here has been using CLM with JavaSSO and have deployed in a clustered application server environment? I've posted in the past regarding this in the OC4J side, but never got a response, so I thought I'd try the experts here...
Here are some TARS that we've logged. Any help from the community would be appreciated.

Thanks!

Hi Kenton,
Specifically, what were the issues that you ran into when clustering JavaSSO? Was it a problem only when combined with the Custom LM?
As long as the same CLM is configured for your app (I assume this is also clustered) and JavaSSO, that should be sufficient. Obviously, CLM need to be configured against the same user repository.
If the apps were on different hosts, did you remember to set the property "custom.sso.cookie.domain" to set the right domain name in the cookie? Otherwise, you will keep getting redirected to the login page.

Dynamic System Resolution and Custom Login Modules
I'm trying to achieve the following, and wondered whether anyone could validate that is possible, and possible solutions.
We want to use Dynamic System Resolution to programatically determine which system alias (and therefore which R3 client) should be returned based on the user. So far so good.
When the user logs in, we want them to be able to specify which R3 client they wish to use whilst logged in to EP. We are considering writing a custom login module to do this, which will strip the client the user wishes to use out of the j_user username, and stores the client value *somewhere* so that the Dynamic System Resolution code can access it and base the system alias it returns on the user's prefered client.
Considering the DSR code only has access to the IUser object it would be handy if our login module could store the prefered client as an attribute in the IUser object. Is it possible to set custom attributes in custom login modules for a given user?
We want to do this to avoid having to have an EP instance per client in a given R3 system, and to avoid duplicating worksets by creating delta linked copies and overriding the client number.
Any suggestions?
Cheers,
SteveHello,
Before even doing such an elaborated construction, I do not succeed in writing a working Dynamic System Resolution.
The service doing the resolution is never called when the method getSystemID() is invoked.
I know that the registry is read (I first test with a system alias which was in the PCD and get an error when debugging, I forget that you cannot use the same system alias in the PCD and in the Dynamic System Resolution service) but afterward the resolving service is not called.
Has anyone an idea ?
Thanks a lot
Best regards

Issues with OSSO ,custom login module and form based authentication
Hi:
We are facing issues with OSSO (Oracle Single Sign on ),Our application use the form based
authentication and Custom login module.
Application is going in infinite loop when we we try to login using osso ,from the logs
what I got is looks like tha when we we try to login from OSSO application goes to the login
page and it gets the remote user from request so it forwards it to the home page till now
it is correct behaviour ,but after that It looks like home page find that authentication is
not done and sends it back to the login page and login page again sends it to the home as it
finds that remote user is not null.
Our web.xml form authentication entry looks like this :
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/jsp/login.jsp</form-login-page>
<form-error-page>/jsp/couldnotlogin.jsp</form-error-page>
</form-login-config>
</login-config>
While entry in orion-application.xml has the following entry for custom login :
<jazn provider="XML">
<property name="custom.loginmodule.provider" value="true" />
<property name="role.mapping.dynamic" value="true" />
</jazn>
Whether If I change the authentication type to BASIC and add the following line
in orion-application.xml will solve the issue :
<jazn provider="XML">
<property name="custom.loginmodule.provider" value="true" />
<property name="role.mapping.dynamic" value="true" />
<jazn-web-app auth-method="SSO" >
</jazn>
Any help regarding it will be appreciated .
Thanks

Custom login module and SSO using 10.1.3.3
We are using ADF 10.1.3.3 to build applications and recently a requirement from a customer was to use LDAP for authentication but use internal application tables for authorisation. So essentially the username and password will be in LDAP but all the roles definition are in the application. This is because the LDAP directory has tight controls on contents and is used enterprise wide.
I created a proof of concept to address this requirement using the examples at
http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm
and also
http://technology.amis.nl/blog/1462/create-a-webapplication-secured-with-custom-jaas-database-loginmodule-deploy-on-jdeveloper-1013-embedded-oc4j-stand-alone-oc4j-and-opmn-managed-oc4j-10g-as
specifically using DBProcLoginModule to call a database package.
The PL/SQL package I created used DBMS_LDAP to call an LDAP directory with the username and password to check authentication and then used internal application tables to get the authorisation details required.
All this worked very well. I tested on both the embedded OC4J and also standalone OC4J.
Then one of my peers said will this work with SSO? Specifically we use Oracle OID as we have SSO for Forms and Reports.
My experience with SSO has been with Oracle OID and having all the user and role details stored within OID.
So my issue now is can I integrate the custom login module approach I have used with SSO? My knowledge of SSO and OID is limited so I'm not sure how (or if) it would interact with a custom login module. Are the two mutually exclusive?
Any guidance is appreciated.
Regards,
AdrianHi,
this question should be posted to the Oracle Application Server forum or the security forum. However, based on my findings and experience in this area, I don't think that SSO is integrated with custom LoginModules since the integration would need to be coded in the LoginModule.

Custom Login Module with Adf 11g and and weblogic server
I have configured adf security on my application. I have checked the authentication and authorization are working fine with the default authenticator.
I am trying to create a custom login module. I have downloaded the custom login module implementation jaasdatabaseloginmodule.zip http://www.oracle.com/technetwork/developer-tools/jdev/index-089689.html. I have added the DBLoginModule.jar to my application. post written by Frank Nimphius and Duncan Mills
I have configured the jps config under the application resources with these entries.
<jpsConfig xmlns="http://xmlns.oracle.com/oracleas/schema/11/jps-config-11_1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.oracle.com/oracleas/schema/11/jps-config-11_1.xsd">

</jpsContext>
When I run the application this custom login is not getting invoked.
I even tried to add these contents to DefaultDomain\config\fmwconfig\jps-config.xml still no result.
Can anyone who has configured custom login module direct me how to correct my application.Hi Frank,
After following the documentation suggested. I am able to create custom authenticator. But when I login I getting the below exception. When I debugged login method returned true. But this error is being thrown after that. Any clue.

Custom Login Module and failover
I'm trying to figure out how to handle authentication when failover from one OC4J to another occurs. I have a custom login module using the example provided by Frank Nimphius (http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm)
I see different results for this "external" custom login module than for either JAZN file store or for the built-in DBTableOraDataSourceLoginModule that comes with OC4J and am wondering why.
Scenario 1 - File authentication using JAZN file store
Results: Works well.
Failover works and when failover occurs, the login page is not displayed. (no 2nd login is required).
Scenario 2 - Custom login module using DB store through the OC4J built-in DBTableOraDataSourceLoginModule
Results: Works well.
Failover works and when failover occurs, the login page is not displayed. (no 2nd login is required).
Scenario 3 (problematic scenario) - Custom login module using DB store through an external login module (not in OC4J). I used the DBTableOraDataSourceLoginModule from Frank
Nimphius with no modifications for this test.
Results: Failover works. But when failover occurs, the login page is displayed and the user has to login again. Question: Why doesn't failover also cover the authentication as in the previous 2 scenarios?
Note: I tried to fix this by adding Java_sso. This does appear to take care of having to log in a second time but raises new issues. One is that authentication is called for every request. Then after the failover occurs, I see a log message indicating the login module aborted but authentication appears to succeed regardless.I'm trying to figure out how to handle authentication when failover from one OC4J to another occurs.

Custom login module with 10.1.3
Hello all,
I've been trying out Frank N's custom login module (http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm) with JDev 10.1.3/OC4J 10.1.3 and am not having much luck.
Whenever I add <property name="role.mapping.dynamic" value="true"/> to orion-application.xml, the application fails to deploy with java.lang.InstantiationException. I even get this error when I try to set up a custom login module using the enterprise manager for OC4J 10.1.3. Is this a bug, or does the doc need to be updated? Without this item configured, I do get the basic login prompt, but no logging or anything - which indicates to me that the custom login module is not even being called. Nothing on metalink either.
Thanks,
Johnhmm i dont know... custom login module (db authentication) definitely works with standalone 10.1.3.0.0 and jdevloper standalone, but it doesnt work with jdev embeded oc4j (jdevstudio1013\jdev\system\oracle.j2ee.10.1.3.36.73\embedded-oc4j)
i have the code, and it works.. however the application is entirerly made in jdev 10.1.3.04 production, it is not migrated from previous jdev.. make sure to deploy from war file (i have prob to deploy from ear)
the only big problem i got is to setup ssl in separate oc4j standalone (ssl works with jdev standalone) and make client athentication to work
because it wont run as it should.. (i did not have this prob in 10.1.2.1) -
SOAP Web Service + Custom Login Module issue
Hi Guys,
We faced an authentication issue in our project. Could you please give any advice how the issue could be resolved.
Environment: A simple SOAP Web Service on top of POJO class created in a Web Application. The web application deployed to the SAP NetWeaver 7.10 Application Server in the Enterprise Application Archive.
Configuration:
Single Service Administration Application(NetWeaver Administration -> SOA Management -> Application and Scenario Communication -> Single Service Administration)
The web service endpoint has authentication configured to use User ID/Password HTTP Authentication.
Authentication Application(NetWeaver Administration-> Configuration Management->Security->Authentication)
The application(<vendorName>/<earName>*<vendor>~<webAppName>) has Authentication Stack configured to use our custom login module.
Issue: BasicPasswordLoginModule used by the J2EE when we are trying to execute the web service using Web Service Navigator(checked in debug mode). It seems that we missed something in configuration.
Idea: The main Idea is to use our custom login module when we are executing a web service.
Could you help me to resolve the issue.
Thanks,
Dmitry

Help - using custom login module with embedded jdev oc4j to access ejb 3
Hi All (Frank ??),
I'm just wondering if anyone has successfully been able to leverage a custom login module in combination
with a client that connects to a local EJB 3 stateless session bean through Jdeveloper 10.1.3.2's embedded oc4j.
I have spent 2+ days trying to get this to work - and i think I resound now to the fact im going to
have to deploy to oc4j standalone instead.
I got close.. but finally was trumped with the following error from the client trying to access the ejb:-
javax.naming.NoPermissionException: Not allowed to look up XXXXXX, check the namespace-access tag
setting in orion-application.xml for details.
Using the various guides available, I had no problem getting the custom login module working
with a local servlet running from JDev's embedded oc4j.. however with ejb - no such luck.
I have a roles table (possible values Member, Admin) - that maps to sr_Member and sr_Admin
respectively in various config files.
I'm using EJB 3 annotations for protecting methods .. for example
@RolesAllowed("sr_Member")
Steps that I had to do so far :-

mshannonThanks for the response. I checked out your blog and tried your suggestions. I'm sure it works well in standalone OC4J, but i was still unable to get it to function correctly from JDeveloper embedded.
Did you ever get the code working directly from JDeveloper?
Your custom code essentially seems to be the equivalent of a grant within system-jazn-data.xml.
For example, the following grant to a custom jaas role (JAAS_ADMIN) that gets added by my custom login module gives them rmi login access :-
<grant>
<grantee>
<principals>
<principal>
<realm-name>jazn.com</realm-name>
<type>role</type>
<class>kr.security.principals.KRRolePrincipal</class>
<name>JAAS_Admin</name>
</principal>
</principals>
</grantee>
<permissions>
<permission>
<class>com.evermind.server.rmi.RMIPermission</class>
<name>login</name>
</permission>
</permissions>
</grant>If I add the following to orion-application.xml
<!-- Granting login permission to users accessing this EJB. -->
<namespace-access>
<read-access>
<namespace-resource root="">
<security-role-mapping>
<group name="JAAS_Admin"></group>
</security-role-mapping>
</namespace-resource>
</read-access>Running a standalone client against the embedded jdev oc4j server gives the namespace-access error.
I tried out your code by essentially creating a static reference to a singleton class that does the role lookup/provisioning with rmi login grant :-
From custom login module :-
private static KRSecurityHelper singleton = new KRSecurityHelper();
protected Principal[] m_Principals;
Vector v = new Vector();
v.add(singleton.getCustomRmiConnectRole());
// set principals in LoginModule
m_Principals=(Principal[]) v.toArray(new Principal[v.size()]);
Singleton class :-
package kr.security;
import com.evermind.server.rmi.RMIPermission;
import java.util.logging.Level;
import java.util.logging.Logger;

}Using the code approach and switching application.xml across so that namespace access is for the group remote_connect, I get the following error from my bean :-
INFO: Login permission not granted for current-workspace-app (test.user)
Thus, the login permission that I'm adding through the custom remote_connect role does not seem to work. Even if it did, i'm pretty sure I would still get that namespace error.
This has been such a frustrating process. All the custom login module samples using embedded JDeveloper show simple j2ee servlet protection based on settings in web.xml.
There are no samples showing jdeveloper embedded oc4j using ejb with custom login modules.
Hopefully the oc4j jdev gurus like Frank can write a paper that demonstrates this.

Custom login module on OC4J 10.1.3.3.0
Hi,
I need to implement custom web form-based authentication on OC4J, in order to port an existing JBoss app. I was following Frank's example at http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm. Trying to access protected pages will correctly redirect to the j_security_check page, and from there call my custom login module - through LoginContext. The issue is that - even if the LoginModule correctly authenticates user's credentials, the request still doesn't get through, coming back to the authentication page.
I perform the deployment using Oracle Enterprise Manager, and the relevant files are:
web.xml:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>testJAAS</realm-name>
<form-login-config>
<form-login-page>/jsp/login.jsp</form-login-page>
<form-error-page>/jsp/login.jsp</form-error-page>
</form-login-config>
</login-config>

<option>

<value>role1</value>
</option>
</options>
</login-module>
</login-modules>
</application>
I assume something is wrong with the deployment configuration, b/c when I specifically add users to the defined role1 role, it works fine(see below). But this is not an option, since users should only be specified in the data store of the LoginModule.
Doing as above, the orion-web.xml is below:
<resource-ref-mapping name="jdbc/lic" />
<security-role-mapping name="role1">
<group name="oc4j-app-administrators" />
<user name="user1" />
<user name="user2" />
</security-role-mapping>
Any insight would be much appreciated. Thanks.Hi,
role to group mapping doesn't seem to work for custom LoginModules. This means hat your web applcation (web.xml) should use th same role names as used on the database authentication. So remove
<security-role-mapping name="role1">
<group name="oc4j-app-administrators" />
</security-role-mapping>
from orion-web.xml and it should start wrking

Custom login module Authentication works but Authorization Does not work
Hi:
I am using custom login module and switched on the ADF authentication using adf-config.xml file. My custom authentication works i.e. it returns true but when it finally tries to display the page 401 Unauthorized message is shown. I am using JDev 10.1.3.2.
Is there any other settings I need to perform. Could you please let me know.
ThanksI have the same issue, please refer to this thread.

How to call custom Login Module from JSP
Hi,
I am stuck with the following issue:
1) Exactly as presented in help.sap.com (http://help.sap.com/saphelp_nw04/helpdata/en/3f/1be040e136742ae10000000a155106/content.htm) I created custom login module and deployed it as a library on J2EE server. When I configured it to be used for my applications in the Security provider but I am getting "No user name provided" exception everytime when my applications use this custom login module.
2) I realized that I would need to call my custom module somewhere within my application (simple JSP) using LoginContext class and then use MyLoginContext.login() spec to initiate login process. But I am not able to pass CallbackHandler parameters from JSP application to my custom login module.
So I have the following questions:
1. Can I pass parameters using LoginContext and CallbackHandler from JSP to my custom login module (created as exact copy of HELP.SAP.COM example) or this module cannot be used this way.
2. How to pass CallbackHandler correctly to my custom login module from JSP. When I am trying to use CallbackHandler, I am getting "Abstract Class cannot be called" error.
I'd appreciate any little help on this matter.
Thanks and regards,
MikeYou have two alternatives to do this:
You can declare your JSP as a protected resource with the use of the deployment descriptors of the application (web.xml) and add the custom login module in the authentication stack of the application. This way, you will use container-based authentication, i.e. the Web Container will enforce the authentication and it will call the custom login module before it dispatches to the JSP. I recommend you this approach because it requires less coding and it makes the whole thing a matter of configuration. The configuration can be later on enhanced or changed runtime without the need to re-build and re-deploy the application. If you choose this approach you can go to the documentation of the server for help on how to modify the login module stack of the application.
You can also use programmatic authentication by using JAAS API. To do this you need to create a custom security policy configuration with login module stack containing the custom login module, and then use the standard JAAS mechanism - new LoginContext(<configuration>, <callback-handler>).login(). This approach requires that you write your own callback handler and handle any LoginException.
Let us know which approach you prefer and whether you have difficulties implementing it! -
J2EE 6.40 Custom Login Module - how to config
hello all,
i am using WAS J2EE 6.40 Sneak Preview edition. Read all i can find about custom login module, in the forum and the online help. still confused. pls help.
here is the background info:
- i am writing a web app. the EAR file contains 5 ejbs, 1 war and bunch of java classes in jars.
- access to my web app is protected through url pattern (in web.xml), i've defined the same named security role in web.xml and on j2ee engine.
- my login module does the user name and password checking. both are stored in database through some other means.
- login is FORM based
following the discussion in another thread on the topic, i did the following:
#1 develop my login module code. packaged it in a jar, then sda file. deploy the sda as a llibrary to the engine.
#2 add my login module to the security store through the security provider service.
#3 configure my web app to use the custom login module in web-j2ee-engine.xml
#4 deploy my web app through the ear file
at this point, in the visual administrator, i can see the library, the custom login module (added to the UME User Store), and also my web app has authentication set to use the custom login module (under policy configurations tab).
now i try to login to my web app. it correctly complains when i enter non-existent user or wrong password and brings me to the login failed jsp page. but when i enter both correctly (as stored in my database), i get http 403 error code. i know it is 403 because i set that error code to a special jsp page in web.xml.
question is why? now i create a user on the j2ee engine with the same name as in my user database. then i can login ok. i am confident that my login module is called since i see the println lines in j2ee engine server logs.
??? so i must be missing something obvious. is it because my web app is protected through security-role? i even tried removing all such roles, but still same problem.
??? or do i completely mis-understand how custom login modules are supposed to work. i thought it means i can authenticate users any way i want without having to use the j2ee engine's user mgmt. pls tell me if i am totally wrong.
??? or maybe my login module code is missing some key stmts. how should it tell the j2ee engine that a user is authenticated? in the login() method, it returns true if user name/passwd match. in the commit() method, it adds the principal to the subject. i don't what else is required.
does anyone have a working scenario using custom login modules?
thanks very much for your inputs and thoughts.
wentaoHi Astrid,
I guess I have the same understanding of JAAS as you. I want to deploy an application that internally makes use of JAAS to authenticate users. There is a LoginModule that authenticates users against some database tables containing all the user data and profile. The application was not designed to be deployed to NetWeaver. So it does not make use of UME or some other NetWeaver specific feature. Actually it handles user management and authoroization issues completely on its own. The only reason for having JAAS is to allow customers to plug in their own LoginModule to use some other kind of user store.
When deploying the web application to a simple servlet engine like Tomcat, all I have to do is to register my LoginModule in the "jaas.conf" file that is parsed by JAAS default implementation. I also tell the JVM where my jaas.conf file is located by appending a "-Djava..." runtime parameter to the JVM startup script.
When using other application servers like IBM WebSphere things become a bit different. Normally you use the administration GUI of that server to configure your LoginModules. WebSphere for example keeps the login configuration in an internal database rather than writing everything into a "jaas.conf" text file. But the way the application can use the LoginModule is the same as in Tomcat.
But when it comes to Netweaver, it seems to me that it's not possible to define a LoginModule that your application can use WITHOUT having to couple it tightly to UME. Or did I get something wrong? Initially I've tried to modify the JVM's parameters (using SAP J2EE Config Tool) to include the location of my "jaas.conf" file containing the my login configuration. But that did not work. The parameter was really passed to the JVM but anyway my LoginModule was not found, I guess that NetWeaver has some own implementation of the JAAS interfaces that just ignore the plain text JAAS configuration files (like WebSphere also does).
The documentation that I have downloaded from SDN doesn't seem to match the 6.4 sneak preview version that I just downloaded some days ago. They say you should deploy your LoginModule as a library and add a refernce to the application. I tried that out but it did not help. The login configuration that the application wants to access is still not found. Actually there seems to be no way to specify the name for a JAAS Login Configuration in NetWeaver. At least I cound not find that in the documentation.
So basically my question is: is it possible to deploy an application that wants to use some own LoginModule (either deployed separately or together with the application, that does not matter) without making use of Netweaver specific features like UME? The application has its own user management infrastructure and just needs a way to setup a JAAS Login Configuration to access its own LoginModule.
Thanks in advance

Problem with role mapping in custom login module
Hi all,
I have developed custom login modules. They don't use the default user store but own data tables holding the necessary user information.
Login works fine. But there is one big problem: Only those users that exist with the same user-id in the default user store get roles assigned to it. Whicht leads to 403-errors in my web application.
Now, this is weired because a user with id 'Susi' has completely different passwords in my custom tables and in the user store, therefore it shouldn't be possible to authenticate 'Susi' against the default user management.
Next thing is, I don't use the default login modules at all. So why does the application validates against the user store?
I thought a source of the problem might be that I don't set the roles correctly. I set the roles as a principal to the subject. I have chosen the role based mapping in the web-engine.xml and mapped all my custom roles to the server role 'guests'.
Could anybody think of a solution to this problem ?
Thanks, AstridAstrid,
Sorry to go off-topic on your post...but I have a question in relation to how you deploy your login module. Do you deploy the login module with your application ? I've developed a login module that I would like to deploy by itself, I currently deploy it with the calculator example and it works fine like this, but I need to deploy it by itself. Any tips you can give would be greatly appreciated.
I've tried to use the deploytool and deploy the module as a library...but I get a "cannot load a login module" in the logs when authenticating a user. -
Callbacks does not work in custom login module
Hi,
We are upgrading portal from 7.01 to 7.31. I am working on custom login module.
I am using NameCallBack, PasswordCallback and httpcallback (prior to upgrade used webCallback which is deprecated in 7.31)
All these three callbacks works fine in our sandbox which uses Portal Database as UME, But same code fails and returns NULL for callbacks in Dev system where we use Active Directory.
//In initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options)
super.initialize(subject, callbackHandler, sharedState, options);
this.callbackHandler = callbackHandler;
// in logion()
NameCallback nameCallback = new NameCallback("User name: ");
PasswordCallback passwordCallback = new PasswordCallback("Password: ", true);
try
callbackHandler.handle(new Callback[] { nameCallback, passwordCallback });
Any ideas will be appreciated.
Thanks,
