looking for a simple configuration file (JAAS)

[Peter Primrose]

Quick JAAS question:

I'm trying to execute a simple code with JAAS. I get this error message:


Exception in thread "main" java.lang.SecurityException: Unable to locate a login configuration

the exception comes from:

  
    public static void main(String[] args) {
        // use the configured LoginModules for the "helloWorld" entry              
    LoginContext lc = null;
        try {
            lc = new LoginContext("helloWorld", new MyCallbackHandler());
        } catch (LoginException le) {
            le.printStackTrace();
            System.exit(-1);
        }
.
.
.
  

I wonder what 'login configuration file' is needed, where should I place it and if anyone has any example

Thank you!

I don't have a direct answer, but this article includes example code showing how to set up and use a login config file. Maybe that's helpful?

Hi Peter,
Maybe http://www.javaworld.com/javaworld/jw-09-2002/jw-0913-jaas.html?page=3 link can give you a bird-eye view of the configuration file required in JAAS.

Hi Peter,
I'm working on the same thing. Here's what I have:

-Djava.security.auth.login.config="C:/absolutePathTo/workspace/ADTest/data/jaas.conf

passed as a VM argument.

Contents of jaas.conf:

/** Login Configuration for the JaasAcn**/
JaasConfig {
com.sun.security.auth.module.JndiLoginModule required debug=true
user.provider.url="ldap://nameOfServer:389/CN=Users,DC=domainName,DC=com"
group.provider.url="ldap//nameOfServer:389/CN=Users,DC=domainName,DC=com"; };    

fwiw, I'm not up and running, but I'm almost positive this is all good info. I think my problem is specific to Active Directory. I had the tutorial running fine till I started trying to authenticate against AD. Best of luck.
