I am using Laserfiche SDK 10.2 JRA to do development

I used the code like below for Kerberos login.

I have configured Kerberos configuration as directed by Laserfiche document.

Following is the sample of the code I used: with servername, repoName, username, password replaced.

---------------------------------------------------------------------------------------------------------------------

String serverName = "server IP", repoName = "repository name", userName = "user name", password = "user password";
        
System.setProperty("java.security.krb5.conf", "C:/Windows/krb5.ini");
System.setProperty("javax.security.auth.useSubjectCredsOnly","true");
System.setProperty("java.security.auth.login.config", "D:/LaserBeam/JRA-Security/jaas.conf");
System.setProperty("sun.security.krb5.debug","true");
Subject subject;
       
        try {
           LoginContext lc = new LoginContext("Client", new LoginCallbackHandler(userName, password));
           lc.login();                                <==== First Login 
           subject = lc.getSubject();
        } catch (LoginException e) {
          System.err.println(e.getMessage());
          return;
        }

        int port = 80;

        // Create a new session
        Session session = new Session();

        // Specify the repository to log in to
        RepositoryRegistration repository = new RepositoryRegistration(serverName, repoName);
        session.logIn(repository, subject);                  <== Second Login

------------------------------------------------------------------------------------------------------------

1) I found that the "First Login" was successful.

Can anybody tell me what I log into? Clearly, it is NOT laserfiche server.

What I am interested is to log into Laserfiche server.

But, the "First Login" was successful without specifying laserfiche server name or ip.

I did debug and found that although the 'First Login" is successful.

The property 'status" of "LoginContext lc " has value of false.

2) I found that 'Second Login" failed with a very long (almost one page) of error messages. Most of them are related to erros in Kerberos.

I think the "Second Login" is the one that actually trying to log into laserfiche server.

However, I do not know why it failed after successful log in of "First Login"/

3) Can anybody show me or tell me what value I should specify in serverName, RepoName, username, and password so that both logins can be successful?

Thanks
