[class][auth]Krb5LoginModule does not work

[John Liu]

Hi all:
I found that Krb5LoginModule does not work.

Here is an example:

First, I set a Kerberos V5 server for this test and add a principal
"[EMAIL PROTECTED]" with password "1111111".

Then I ran next segment of code:

Krb5LoginModule krb5Login = new Krb5LoginModule();
Map<String,String> options = new HashMap<String,String>();
options.put("principal", "[EMAIL PROTECTED]");
Subject subject = new Subject();
krb5Login.initialize(subject, new TextCallbackHandler(), null, options);
krb5Login.login();
krb5Login.commit();

with following vm arguments:
-Djava.security.krb5.realm=EXAMPLE.COM
-Djava.security.krb5.kdc=<kdc ip address>:88
-Djavax.security.auth.useSubjectCredsOnly=false

The exception was thrown as follows:

javax.security.auth.login.LoginException
    at org.apache.harmony.auth.module.Krb5LoginModule.login(
Krb5LoginModule.java:141)
    at

    at org.apache.harmony.auth.module.Krb5LoginModule.login(
Krb5LoginModule.java:96)

I've reported it on jira HARMONY-4921. Is there anyone familar with it could
help to have a look at it?

Thanks,
John
