J_security_check in form-based authentication - not checking for blank passwords

I am using the LDAP Security Realm to authenticate against an iPlanet
Directory Server. All works as expected when a user-id and password
are entered for form-based authentication.
However, when a userid is entered but no password, j_security_check
logs the user in successfully. Aparently, this is correct LDAP
behaviour as anonymous login to the LDAP server is permitted. It seems
that the j_security_check servlet should check for blank passwords
before trying to authenticate against the LDAP server and fail
authentication if this is the case.
Has anyone else experienced this problem?

Hi Brian,
I do not believe it is j_security_check's job to check for blank
passwords.
In many security realms, it is "legal" for a user to have a blank
password. j_security_check forwards whatever password was entered so that
even users with blank passwords can be authenticated by the realm on the
backend. For this reason I believe that j_security_check is "doing the
right thing" by just forwarding whatever is presented to it, rather than
having its own logic. It is best if j_security_check just acts as a very
dumb middle man.
If behavior was altered, it is true that your particular problem would be
solved, but then many other people would have a problem with their users
with blank passwords authenticating properly...
Try looking into how to disable anonymous logins on the LDAP end of
things. Hope this helps.
Cheers,
Joe Jerry

Logout Functionality in Form Based Authentication Not Working Properly

Hi All,
I am using Form Based Authentication in ADF. In this I followed the following steps:-
1.Login On Page.
2.In successful login page ,copy the url
3.Click on "Logout"
4.Paste the url in login page and click enter
5.System taking me back to that page where I can perform all the actions.
But the Login operation should not happen just by entering the url. Please provide any help how to stop redirecting to my authenticated page just by typing the url. This is a big security constraint.Any Assistance to this is highly appreciated.
Thanks & Regards

Hi BaiG,
For Login I am using the form based authentication and for logout here is my code:-
public void logout() {
ExternalContext ectx =
FacesContext.getCurrentInstance().getExternalContext();
HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
HttpSession session = (HttpSession)ectx.getSession(false);
session.invalidate();
response.setHeader("Cache-Control", "no-cache");
response.setHeader("expires", "0");
response.setHeader("Pragma", "no-cache");
try {
response.sendRedirect("AdminLogin.html");
} catch (IOException e) {
logger.severe(e.getMessage());
//Inform JSF to not take the response in hands
FacesContext.getCurrentInstance().responseComplete();
logger.info("session invalidated");
Thanks,

Session expired message in form based authentication

Hi, i m using JAAS form based authentication on jboss for our application and we want session expired message to show in the login form when it loads for authentication after session expired.
do any one have any idea how to achive this as the application will never be able to detect that the session expired as it will always have a valid session available becoz ,When an HTTP session expires and the client makes a request to any secured resource, the JAAS subject will not be found for authorization. At this point, the security framework creates a new HTTP session, stores the target URL value in the session, and then redirects the user to the login page. After a successful login process, the user is forwarded back to the target page,
but our Web applications may need to capture these session expiration events and show some custom message to the user.
HTTP session listener doesn't work here as HTTP session listener does not allow you to create a new session.
Thanks in advance

ObSSOCookie does have session time data. Access Manager SDK can parse the cookie and can access it's own settings for max and idle session time.
Trick is, once the user is logged out, the cookie is destroyed. I suspect there is no real practical way to do this.
I have pondered the idea that you could use AJAX to communicate with a service that uses the SDK to return data about current session state - "You have 40 seconds left to get your form filled out, buddy! 39, 38, 37..."
Oh to have that much free time... ;)

How to redirect to j_security_check without the form based authentication

Hi,
I am trying to integrate my application authentication to a backend system with the ibm websphere form based authentication. Below is the scenario:
1. when the user clicks on a protected url, the container will redirect the user to the login page.
2. instead of displaying the login page, i would like to automatically redirect the user to j_security_check action. which means that instead of displaying the login.jsp page, the user will automatically be redirected to j_security_check to perform some user authentication, and if successful, the application pages will be displayed.
The reason i want to auto redirect the user to j_security_check is because i am implementing some integration work with a backend system. the user will key in the username/password from another system. once the user is authenticated, the user information will be passed to my system. The login page of my system will not be displayed again, and by using the username value, my system will assume that the user has successfully been authenticated (authentication done by the backend system), and therefore automatically gain authorization to login into my application.
i hope that clarifies my problem.
anyone out there has any solution to my problem?
thanks a lot in advance.

Hi Darren,
Let me explain the whole authentication environment.
There are actually 2 systems in this environment. Let;s call it system A and system B.
System B is actually using the authentication mechanism that i described in my previous message.
A login page will be presented to the user (within system A). User credential is collected and passed to system A to be authenticated. System A will use its own mechanism to authenticate the user.
Once the user is authenticated, system A will pass the user ID to system B. At this point, system B will assume that the user is authenticated and grant authorization to access the application. (system B global security is enabled and implements the form based authentication mechanism) Therefore, at this point, the redirect page (so called login page) will not be displayed to the user, instead it will be automatically redirected to the j_security_check action to execute the customer Ldap Registry class. (ps : eventhough authentication is no longer needed, the flow will still go to Ldap Registry class. A check is done in the Ldap Registry class to skip the authentication, if it is not boot strap login. Only first and only time authentication is done for boot strap login).
In the case a protected url is clicked or invoked by the user directly, the application will redirect the user to the initial login of system A. Otherwise (the url link originates from system A, during the passing of user token to system B), system B will redirect to j_security_check and execute the customer Ldap Registry class.
Based on the above explained scenario, in your opinion, is there any security loopholes? consider that system B no longer perform authentication but only to grant authorization to the user.
Appreciate your advice. Thanks in advance
Anyway, i am using the ibm websphere server. :)

Ask for help with form based authentication & authorization

Hi:
I encountered the following problem when I tried the form based authentication & authorization (see the attached part of the config files, web.xml, weblogic.xml & weblogic.properties)
1. authorization seems not invoked against the rules specfied, it doesn't go the login error page as long as the user/pwd match, even though the user does not have the necessary role
in the example below, user3 should be denied to access the signin page, but seems no login error page returned, actually I never see any page / error message which complain about the authorization / access control error
2. after authenticate correctly, always get redirected to the / (context root) url, instead of the url prior the login page, for e.g., signin page
Any idea ?
Thanks in advance.

Hi, Paul:
Thanks a lot for your reply.
Firstly let me just correct a little in the attachment I put previously, I think I missed following lines :
<auth-constraint>
<description>no description</description>
<role-name>customer</role-name>
</auth-constraint>
So, user1 & user2 are in the customer group, but user3 not, and /control/singin is protected by this security constraint, as a result, when anyone click the link to /control/singin, he was led to the login page, if he tries to login as user1 & user2, he should pass & led to original page (in this case /control/singin, and my code's logic, once /control/signin is used, means that he already login successfully & redirected to the login success page), but if he tries to login as user3, he should only pass the authentication check, but fail the authorization check, and led to login error page.
What not happen are :
1. user1 & user2 pass, but redirect to /
2. user3 also pass, because I see that debug message shows also get redirected to /, instead of login error page
(login error page will be displayed, only if I try to login as a user with either wrong userid, or wrong password)
3. one more thing I notice after I first time post the message, the container does not remember the principal, after 1. is done, not even for a while
And the similar configuration works under Tomcat 3.2.1, for all 3. mentioned above.
Any idea ?

If I understand what your trying to do, everyone should get access to the

you specified in the XML files,

The principal customer_group (and therefore its members) is mapped in the

customer.
I can't speak to the reason your being redirected to the document root.

Hello.
I'm trying to setup Form-based Authentication. I keep reading the same (limited) documentation about putting this in your server's .xml files:
<form method="POST" action="j_security_check">
<input type="text" name="j_username">
<input type="password" name="j_password">
</form>I don't even have a web.xml or sun-web.xml file. I cannot find examples of Sun One WS either.
Any sample coding - including yoru web.xml, sun-web.xml - would be greatly appeciated.

Form-based authentication problem with weblogic

Hi Everyone,
The following problem related to form-based authentication
was posted one week ago and no reponse. Can someone give it
a shot? One more thing is added here. When I try it on J2EE
server and do the same thing, I didn't encounter this error
message, and I am redirected to the homeage.
Thanks.

I am using weblogic5.1 and RDBMSRealm as the security realm. I am having the following problem with the form-based authentication login mechanism. Does anyone have an idea what the problem is and how to solve it?
When I login my application and logout as normal procedure, it is OK. But if I login and use the browser's BACK button to back the login page and try to login as a new user, I got the following error message,
"Form based authentication failed. Could not find session."
When I check the LOG file, it gives me the following message,
"Form based authentication failed. One of the following reasons could cause it: HTTP sessions are disabled. An old session ID was stored in the browser."
Normally, if you login and want to relogin without logout first, it supposes to direct you to the existing user session. But I don't understand why it gave me this error. I also checked my property file, it appears that the HTTP sessions are enabled as follows,
weblogic.httpd.session.enable=true

Hi...
Hehe... I actually did implement the way you implement it. My login.jsp actually checks if the user is authenticated. If yes, then it will forward it to the home page. On the other hand, I used ServletAuthentication to solve the problem mentioned by Cameron where Form Authentication Failed usually occurs for the first login attempt. I'm also getting this error occasionally. Using ServletAuthentication totally eliminates the occurence of this problem.
I'm not using j_security_check anymore. ServletAuthentication does all the works. It also uses RDBMSRealm to authenticate the user. I think the biggest disadvantage I can see when using ServletAuthentication is that the requested resource will not be returned after authentication cause the page returned after authenticating the user is actually hard coded (for my case, it's the home.jsp)
cheers...

Hi Jerson,
I tried your code this weekend, it didn't work in my case. But
I solved my specific problem other way. The idea behind my problem is that the user tries to relogin when he already logs in. Therefore, I just redirect the user into another page when he is getting the login page by htting the BACK button, rather than reauthenticate the user as the way you did.
But, I think your idea is very helpful if it could work. Problems such multiple concurrence logins can be solved by pre-processing.
In your new code, you solved the problem with a new approach. I am just wondering, do you still implement it with your login.jsp file? In other word, your action in login.jsp is still "Authenticate"? Where do you put the URL "j_security_check"?
Thanks.

Jerson,
First try it redirected (raw) to see if that indeed is the problem ... then
if it works you can "fix" it the way you want.

Hi...
Thanks for your suggestion... I've actually thought of that solution. Butusing page redirection will expose the user's password. I'm thinking of
another indirection where I will redirect it to another servlet but the
password is encrypted.
What do you think?
thanks....

Maybe redirect to the current URL after killing the session to let the
request clean itself up. I don't think that a lot of the request (such
as
remote user) will be affected by killing the session until the nextrequest
comes in.

Hello guys...
I've a solution but it doesn't work yet so I need your help. Because
one
of the reason for getting form base authentication failed is if an
authenticated user tries to login again. For example, the one mentionedby
John using the back button to go to the login page and when the user logsin
again, this error occurs.
So here's my solution
Instead of submitting the page to j_security_check, submit it to a
servlet
which will check if the user is logged in or not. If yes, invalidates its
session and forward it to j_security_check. But there's a problem in this
solution, eventhough the session.invalidate() (which actually logs theuser
out) is executed before forwarded to j_security_check, the user doesn't
immediately logged out. How did I know this, because after calling
session.invalidate, i tried calling request.RemoteUser() and it doesn't
return null. So I'm still getting the error. What I want to ask you guyis
how do I force logout before the j_security_check is called.
here's the code I did which the login.jsp actually submits to
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class Authenticate extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponseresponse)
throws ServletException, java.io.IOException {
if (request.getRemoteUser() != null) {
HttpSession session = request.getSession(false);
System.out.println(session.isNew());
session.invalidate();
Cookie[] cookies = request.getCookies();
for (int i = 0; i < cookies.length; i++) {
cookies.setMaxAge(0);
getServletContext().getRequestDispatcher("/j_security_check").forward(reques
t, response);
public void doGet(HttpServletRequest request, HttpServletResponseresponse)
throws ServletException, java.io.IOException {
doPost(request, response);
let's help each other to solve this problem. thanks.

John,
1. You are using a single WL instance (i.e. not clustered) on that
NT
box
and doing so without a proxy (e.g. specifying http://localhost:7001),
correct?
2. BEA will pay more attention to the problem if you upgrade to SP6.If
you don't have a reason NOT to (e.g. a particular regression), then
you
should upgrade. That will save you one go-around with support: "Hi,I
am
on SP5 and I have a problem.", "Upgrade to SP6 to see if that fixes
it.
Call back if that doesn't work."
3. Make sure that you are not doing anything special before or after
J_SECURITY_CHECK ... make sure that you have everything configuredand
done
by the book.
4. Email BEA a bug report at [email protected] ... see what they say.

Cameron,
It seems to me that the problem I encountered is different a little
from
what you have, evrn though the error message is the same eventually.
Everytime I go through, I always get that error.
I am using weblogic5.1 and sp5 on NT4.0. Do you have any solutions
to
work
around this problem? If it was a BUG as you
pointed out, is there a way we can report it to the Weblogic
technical support and let them take a look?
Thnaks.

John,
I will verify that I have seen this error now (after having read
about it
here for a few months) and it had the following characteristics:
1) It was intermittent, and appeared to be self-curing
2) It was not predictable, only seemed to occur at the first
login
attempt,
and may have been timing related
3) This was on Sun Solaris on a cluster of 2 Sparc 2xx's; the
proxy
was
Apache (Stronghold)
4) After researching the newsgroups, it appears that this "bug"
may
have gone away temporarily (?) in SP5 (although Jerson Chua
<[email protected]> mentioned that he still got it in SP5)
I was able to reproduce it most often by deleting the tmpwar and
tmp_deployments directories while the cluster was not running,
then
restarting the cluster. The first login attempt would fail(roughly
90%
of
the time?) and that server instance would then be ignored by the
proxy
for a
while (60 seconds?) -- meaning that the proxy would send all
traffic,
regardless of the number of "clients", to the other server in thecluster.
As far as I can tell, it is a bug in WebLogic, and probably has
been
there
for quite a while.

Hi Everyone,
The following problem related to form-based authentication
was posted one week ago and no reponse. Can someone give it
a shot? One more thing is added here. When I try it on J2EE
server and do the same thing, I didn't encounter this error
message, and I am redirected to the homeage.
Thanks.

I am using weblogic5.1 and RDBMSRealm as the security realm. I
am
having
the following problem with the form-based authentication login
mechanism.
Does anyone have an idea what the problem is and how to solve it?
When I login my application and logout as normal procedure, it
is
OK.
But
if I login and use the browser's BACK button to back the login
page
and
try
to login as a new user, I got the following error message,
"Form based authentication failed. Could not find session."
When I check the LOG file, it gives me the following message,
"Form based authentication failed. One of the following reasons
could
cause it: HTTP sessions are disabled. An old session ID was stored
in
the
browser."
Normally, if you login and want to relogin without logout first,
it
supposes to direct you to the existing user session. But I don'tunderstand
why it gave me this error. I also checked my property file, it
appears
that
the HTTP sessions are enabled as follows,
weblogic.httpd.session.enable=true

Form Based Authentication in SharePoint 2013: Getting The remote server returned an error: (500) Internal Server Error

Hi
I configured forms based authentication mode in Sharepoint 2013 site. When i tried to log in with windows authentication prompt it throws the following error
The remote server returned an error: (500) Internal Server Error

How to fix this issue?

Did you create a new web application or modify an existing web application?
I would start by checking the ULS logs, maybe there is an incorrect setting within one of the web.config files, or SQL permissions.
Also, as suggested above, check application pools are running.

FORM based Authentication issue on Sun ONE AS7

I am trying to use FORM based authentication for a web module I created, and can not get it to work. I have registered the roles through the admin console of the server, and adjusted the web.xml. When I try to use BASIC authentication, I get a 'Authentication refused for []' message before I even log in, and another one after I do. When I use FORM authentication, the URL points to my login.jsp page (no matter what I put in the path, which is what is supposed to happen), however my default servlet (hello.java) is actually run, and the login.jsp page never comes up. I created my jsps and servlet in the mounted [ejb]_WebModule. Please let me know if something seems incorrect here, or if you can think of something I should check...I can't find anything out there to help me.
Here is my web.xml:
<web-app>
<display-name>DiningGuideManager_TestApp</display-name>
<servlet>
<servlet-name>front</servlet-name>
<servlet-class>data.DiningGuideManager_WebModule.hello</servlet-class>
</servlet>
<servlet>
<servlet-name>myPage</servlet-name>
<jsp-file>/myPage.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>front</servlet-name>
<url-pattern>/*</url-pattern>

<session-config>

<role-name>EveryoneElse</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>default</realm-name>
</login-config>
<security-role>
<role-name>Me</role-name>
</security-role>
<security-role>
<role-name>EveryoneElse</role-name>
</security-role>
<ejb-ref>
<ejb-ref-name>ejb/TestedEJB</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>data.DiningGuideManagerHome</home>
<remote>data.DiningGuideManager</remote>
<ejb-link>DiningGuideManager</ejb-link>
</ejb-ref>
</web-app>
for FORM authentication I have this:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>default</realm-name>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.jsp</form-error-page>
</form-login-config>
</login-config>
Thanks,
Michelle

Yes there's a default generated index.jsp page that I'm having trouble overriding with one of my own. Have you used Form Based Authentication before? To do so you have edit the WEB-INF/web.xml file by adding:
<security-constraint>
<web-resource-collection>
<web-resource-name>Secure Area</web-resource-name>
<url-pattern>/test/secure/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/test/secure/loginpage.jsp</form-login-page>
<form-error-page>/test/secure/errorpage.jsp</form-error-page>
</form-login-config>
</login-config>
When you attempt to first go to any page in my /test/secure/ directory you get redirected to the /test/secure/loginpage.jsp where you have to login as a tomcat user, when succesfully logged on you get redirected to an index.jsp page which is NOT the one I created in test/secure/index.jsp. Even when I type in the url to go to my own test/secure/index.jsp I still don't get my own one that exists there, but instead get the default one that's generated that displays:
"Authentication Mechanism FORM".
Hope that makes more sense.
I've tried restarting tomcat but it makes no difference.
