RE: RE : RE : RE : RE : RE : how to access Subject after authenti fica tion
instead of using something like
JAVA_OPTS=-DJAVA_OPTS=-Djava.security.auth.login.config=%CATALINA_HOME%\conf
\Sample_jaas.config
to locate your jaas config file, you could edit the java.security file of
the jre used by Tomcat instead, you are likely to find this file somewhere
like:
%java_home%\jre\lib\security\java.security
add the following line in this file
login.config.url.1=file:///%CATALINA_HOME%\conf\Sample_jaas.config
(you might have to type the full path, rather than use %catalina_home%, I
dont know)
or make it .2 if there is a .1 entry etc

The command line is ok !
But I have an exception :
Caused by: java.io.IOException: Impossible de trouver une
configuration de
connexion
Hehe :-) Pas mal comme message d'erreur ;-)
at
com.sun.security.auth.login.ConfigFile.init(ConfigFile.java:206)
at
com.sun.security.auth.login.ConfigFile.init(ConfigFile.java:95)
... 33 more
I set
JAVA_OPTS=-DJAVA_OPTS=-Djava.security.auth.login.config=%CATA
LINA_HOME%\conf
\Sample_jaas.config
I never used JAAS this way so I cannot help you. Are you
trying to load
the file from your webapp? Hav eyou try to put the file
inside the war?
-- Jeanfrancois
The classe that instantiates the login context is located in
common/classes
The standard Catalina.policy containts this permission
grant codeBase file:${catalina.home}/common/- {
permission java.security.AllPermission;
};
Any ideas ?
Thanks in advance!

You need to start Tomcat using the -security

Are you both running with the security manager on? I think
that's the
problem...

Matt I am ok with you! I try the two methods and I have

(null) !
Perhaps we have to configure properly tomcat (?) so that
it can record the
subject in the session. Perhaps an authenticator ?
Jean François ! any ideas ?
The second method is
Subject.getSubject(java.security.AccessController.getContext());

Two ways:
httpSession.getAttribute(javax.security.auth.subject)
or
Subject.getSubject(AccessControl.getContext())

But, if, as I suspect, this is not part of the current

I work around this by concatenating all the information I

RE: how to access Subject after authentification
Hi I had a similar question a while back and never really got it fully resolved, but I found that Tomcat doesn't save the subject as a session attribute. However in your case you don't need to access the subject. In the web.xml file for your app, you can define what roles have access to each resource (jsp, servlet) and have your JAAS login module assign these roles to the subject - i.e. container managed security. e.g. add to web.xml (gives access to logins with role user to all of your application): security-constraint web-resource-collection web-resource-namemyApplication/web-resource-name url-pattern/*/url-pattern /web-resource-collection auth-constraint role-nameuser/role-name /auth-constraint /security-constraint security-role role-nameuser/role-name /security-role see the tomcat docs for more info Matt -Original Message- From: LERBSCHER Jean-Pierre [mailto:[EMAIL PROTECTED] Sent: 20 July 2004 14:42 To: '[EMAIL PROTECTED]' Subject: how to access Subject after authentification Hi, I am using JAAS authentification module to authenticate user within tomcat 5.0.27.

RE: Accessing javax.security.auth.Subject within a session
Thanks for your reply Jeanfrancois, but I need more help !! - I know from the Javadocs the syntax for getting a subject from a login context, and the login context from an Access controller, but how do you access the particular login context and/or access controller for a logon. -also I understand that I can store the subject as a session attribute, but does Tomcat automatically store the subject as a session attribute? Matt Can anybody tell me how to access in my servlets the javax.security.auth.Subject object generated at login? You can get it using Subject.getSubject(AccessController.getContext()) Tomcat 5 store the Subject as an attribute.

Accessing javax.security.auth.Subject within a session
Hi I've implemented a JAAS Realm authentication module for my servlet/JSP web-app which is working a treat. Can anybody tell me how to access in my servlets the javax.security.auth.Subject object generated at login? This fronts an existing application and I would like to store the user-specific jdbc database connection object generated at login as a credential within the Subject and use it within the session context of my web-app. I know that I could capture the username and password with a filter and recreate the db connection post authentication, but I guess this kind of defeats the purpose of container based security and creates unnecessary session creation work at the database.
