Form Based Authentication in Tomcat, getting login and password

Sorry for my English.
How I can guess login and password strings of an user, from error page (JSP)using "Form Based Authentication of Tomcat"?
I need know it to lock the count each 3 error tries (if login is ok but
password is bad, insteed).
Methods 'getRemoteUser', 'isUserInRole' and 'getUserPrincipal' of
HttpServletRequest interface have this result: If no user has been
authenticated, returns null, false and null respectly. For this reason, they aren't utils for me.
If I don�t know login what user writed, I can't lock his/her count.
Exist solution for this? Thanks

hi i am also facing the same problem. could u please tell me how u overcame the situation ?
u will reallly pull me out of my troubles
thanx in advance

Form Based Authentication on Tomcat with custom index.jsp page...

Hi there ppl,
I've got Form Based Authentication working correctly on my Tomcat server but I want to override the default generated index.jsp after successfully logging on. I've tried placing my own index.jsp in the directory that's restricted, but its only overridden by the default one when successfully logged on which displays:
"Authentication Mechanism FORM"
This means having to navigate by typing the url in the address bar to another page which is gets really annoying afterawhile.
Any help on this would be much appreciated,
thanks already

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.

Form Based Authentication without login page

Hi,
i need to use form based authentication in a web page, but without a dedicated login page. So basicly every page will contain a login form in the upper right corner, so the user can login anytime in his browsing session directly from the page he's reading.
I am aware of that the form based authentication config needs a login and a error page.
I need some hints on how this could be implemented so that i dont need them directly. Im quite sure this is possible, if any of you has ideas please share them with me.
dukes are waiting ...

sorry - double posted : http://forum.java.sun.com/thread.jspa?threadID=584579&tstart=0

Form-based authentication and JSF

I am trying to use a form-based authentication in Tomcat 6, and from what I understand the page that contains the login form can not be a JSF page.
The problem I'm having with this is that I need the client's username and password accessible from my backing bean, but I don't know how to put them there from a standard JSP.
Before all this, I had a simple login form with username/password fields that were bound to a bean, and a button that executed a bean method that would perform the login procedure, retrieve the client's data from the DB and create a Client object in the session to be accessible throughout the application. Now, I need to use container managed access control with form-based authentication, and I know how to set it up but don't know how to create the Client object if the container does all the authentication and I never even get a hold of a username/password combination let alone the rest of the client's data.
Any advice on this would be greatly appreciated.

FORM Based Authentication and Browser Refreshing

We are using FORM Based Authentication in our web application and it works rather well. I have noticed an interesting bit of behavior that I am unable to explain. After an attempt is made to access the first protected resource the container will display the login page specified in the web.xml file. After successful authentication the original protected resource is displayed as expected. In the Address line of the browser however the original URI requested is now replaced with the following:
http://<domain>:<port>/<root>/j_security_check
Now, when we hit the refresh button on the browser we get the following error:
404 Not Found
Resource /<domain>/j_security_check not found on this server
Two questions. 1. why does it do this? and/or (more importantly) 2. How do I prevent this behavior or work around it?

I�m trying to figure out how to pass the user�s ID
and password, using form-based authentication and
file realm, to our JDBC connection. Two separate issues.
I've usually seen it done where there are three tiers, of course. The user provides login credentials from the view tier, which are passed to the controller tier. The controller will validate the user against a database or LDAP. Once they're validated, the credentials are put into session and provided for all apps that need them, including the persistence tier.
The connection pool requires that you create connections using an application ID, not the user ID. You have to move the security out of the database and into the application.

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

Form based authentication getting logged in username and role

Hi
I have implemented a simple Form based authentication in my web site.
I have maintained tomcat-users.xml file for user names, passwords and roles.
Once my user is authenticated, I need to access his name and role in website.
How can this be done.
Please guide.
Thanks

The request object should contain the information, e.g. use request.getRemoteUser().

Get user and user-roles in form based authentication

How do I get user and roles associated with the user in my bean for "form based authentication".

HttpServletRequest#getUserPrincipal().
This has nothing to do with JSF. Form based authentication is part of Servlet spec.
In JSF you can get the HttpServletRequest by ExternalContext#getRequest().

Get j_username in form based authentication

I would like to get access to j_username when form-based authentication fails, i.e. if the user does not enter a valid username/password combination. What is best way to do this. I have looked in this forum and have seen mention of using servlets, filters, SAAJ, etc. Example code would be much appreciated.
Martin

hello all,
I am using WebSphere and some how my filter is not being invoked, although my form based authentication works fine !!
I am trying to do some post login in the filter but my filter isnt called....
My filter is defined as follows
     <filter>
          <filter-name>LoginFilter</filter-name>
          <display-name>LoginFilter</display-name>
          <filter-class>pkg.LoginFilter</filter-class>
     </filter>
     <filter-mapping>
          <filter-name>LoginFilter</filter-name>
          <url-pattern>/j_security_check</url-pattern>
     </filter-mapping>What am I doing wrong??
Also is there a possibiity that i can call my action class from the filter by mapping my action class as a servlet mapping to the filter?
if so, how can i do it ?

Get authenticated programmtically in FORM-based authentication

Hi, friends,
Does anybody know how to get authenticated programmtically when access some servlet
in FORM-based authentication ?
I have some Java programs running on a server other than weblogic application
server. And I want to use HTTP request programmtically to talk to a servlet on
WebLogic 6.0. For basic authentication, i can add authorization info into the
request, how can I do that for form-based authentication ?
Thanks
John

Hi John,
Yep, it's WebLogic-specific.
Check out

SP4 and Form Based Authentication

Hi,
I had just advised a customer to apply SP4 to WLS and
then plug in the 'source code' patch, he replied that he had
been informed that SP4 breaks Form Based Authentication for
war web apps?
Can anyone confirm/deny this for me please ?

Hehe Hiya Patrick!, that was Me! seems we use the same hot source of info :)

MOBI SSO with trusted authentication and form based authentication

Dear All,
I am trying to configure Trusted authentication based SSO FOR MOBI, here are the details:
- SAP BI 4.1 SP04
- Trusted authentication with HTTP header configurred for BI Launchpad and working fine.
Now to have SSO from Mobile, I plan to leverage the existing configuration of BI Launchpad and at Mobile level, I want to use authentication type as TRUSTED_AUTH_FORM, instead of TRUSTED_AUTH_BASIC, with the approach: Trusted authentication with HTTP header.
And
Provide our app users their X502 certs.
1. Will the above approach work ??
2. As per SAP NOTE: 2038165 - SSO using form based trusted auth gives with the SAP BI app for iOS gives error MOB00920 this does not work and is still under investigation from July last year ? So for any community member, has this been found working ??
I would appreciate your valuable inputs.

Sarvjot Singh

Hi,
According to your post, my understanding is that you want to know the difference of the SharePoint three type user authentications.
Windows claims-based authentication uses your existing Windows authentication provider (Active Directory Domain Services [AD DS]) to validate the credentials of connecting clients. Use this authentication to allow AD DS-based accounts access to SharePoint
resources. Authentication methods include NTLM, Kerberos, and Basic.
Forms-based authentication can be used against credentials that are stored in an authentication provider that is available through the ASP.NET interface
SAML token-based authentication in SharePoint 2013 requires coordination with administrators of a claims-based environment, whether it is your own internal environment or a partner environment.
There is a good article contains all the SharePoint Authentications, including how they work and how to configure.

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.
