Cannot Create Logincontext. Configuration Error
Contents |
Authorization Service (JAAS) was introduced as an optional package to the Java 2 SDK, Standard Edition (J2SDK), v 1.3. JAAS has now been integrated into the J2SDK 1.4. JAAS can be used jaas.config example for two purposes: for authentication of users, to reliably and securely determine com.sun.security.auth.module.krb5loginmodule required who is currently executing Java code, regardless of whether the code is running as an application, an applet, a

bean, or a servlet; and for authorization of users to ensure they have the access control rights (permissions) required to do the actions performed. This section provides a basic tutorial for the
Jaas.config Tomcat
authentication component. The authorization component will be described in the JAAS Authorization tutorial. JAAS authentication is performed in a pluggable fashion. This permits Java applications to remain independent from underlying authentication technologies. New or updated technologies can be plugged in without requiring modifications to the application itself. An implementation for a particular authentication technology to be used is determined at runtime. The implementation is jaas.conf kerberos specified in a login configuration file. The authentication technology used for this tutorial is Kerberos. (See Kerberos Requirements.) The rest of this tutorial consists of the following sections: The Authentication Tutorial Code The Login Configuration Running the Code Running the Code with a Security Manager If you want to first see the tutorial code in action, you can skip directly to Running the Code and then go back to the other sections to learn about coding and configuration file details. The Authentication Tutorial Code Our authentication tutorial code is contained in a single source file, JaasAcn.java. This file's main method performs the authentication and then reports whether or not authentication succeeded. The code for authenticating the user is very simple, consisting of just two steps: Instantiate a LoginContext. Call the LoginContext's login method. First the basic code is shown, followed by a complete listing of the JaasAcn.java source file, complete with import statements and error handling. Instantiating a LoginContext In order to authenticate a user, you first need a javax.security.auth.login.LoginContext. Here is the basic way to instantiate a LoginContext: import javax.security.auth.login.*; . . . LoginContext lc = new

Jaas.conf Keytab
to test your framework, so I began by following your "Jspresso in 10 java.security.auth.login.config classpath minutes" tutorial. After I understood that i needed to install python on my computer, I succeeded to have my helloworld javax.security.auth.login.configuration example war. So I deployed it in Tomcat, and it works great ! But I can't log in my application. In the Catalina console, I have this error : "Cannot create LoginContext. Impossible de http://docs.oracle.com/javase/7/docs/technotes/guides/security/jgss/tutorials/AcnOnly.html trouver une configuration de connexion" That's the only log I found. Could you help me ? PS : in the tutorial, I didn't care about ULC and GraphVIZ, because I thought that it wasn't necessary. Thanks, Disklad. April 27, 2010 at 10:17 #1854 vvandensKeymaster Hi Disklad, First of all, welcome to Jspresso ! As you noticed it, the website tutorials haven't been updated yet to http://www.jspresso.org/forums/topic/solved-logincontext-problem/ reflect 3.5.x upcoming changes (we will update the site for the GA release). That explains the missing python installation directions. Python is actually required for the Qooxdoo frontend (that was not available for 3.0.0). Regarding your problem, the tomcat JVM is certainly missing the system property -Djava.security.auth.login.config=${TOMCAT_HOME}/conf/jaas.config Please double-check that you have precisely followed the begining of the section named "Deploying the application in the servlet container". Once you've succesfully deployed, you will also be able to check the Qooxdoo frontend by using the following URL : http://localhost:8080/helloworld-webapp/qooxdoo/ HTH, Vincent April 27, 2010 at 12:15 #1855 Legacy UserSpectator Thanks ! my bad, I didn't set the JAVA_OPTS on the right line. But I still have an issue : "Cannot create LoginContext. Impossible de développer ${TOMCAT_HOME}/conf/jaas.config correctement" I tried to modify the jaas.config but it doesn't work. Here is my jaas.config : helloworld { org.jspresso.framework.security.auth.spi.DevelopmentLoginModule required user=demo password=demo roles="administrator" custom.language=fr;}; nothing else. The ${TOMCAT_HOME} is set to C:Program Filesapache-tomcat-6.0.26 April 27, 2010 at 13:06 #1856 vvandensKeymaster Can you confirm that you have the exact following line in startup.bat - with ${TOMCAT_HOME} substituted by the install root of tomcat as explained at the begining of the tuto : -Djava.security.auth.
