wM82 : How to configure Kerberos V5?


I would like to single sign on using Kerberos V5 / SPNEGO.

Is possible? Is there any description?

One way to make Kerberos available at a Java1.6 runtime environment is to load a krb5.conf and a login.conf at startup. To do so it is necessary to set the environment variables “-Djava.security.krb5.conf=krb5.conf”, “-Djavax.security.auth.useSubjectCredsOnly=false” and “-Djava.security.auth.login.config=spnegoLogin.conf” somewhere. I extended the server.bat (wM8.2) but after startup the settings are not available.

I am refering to http://download.oracle.com/javase/6/docs/technotes/guides/security/jgss/lab/part6.html . This article describes a simple example of Kerberos with onboard Java utilites. But the precondition is to execute the example class like this …

java -Djava.security.krb5.conf=krb5.conf

Does the IS override the -Djava.security settings while starting up?

Thank you in advance,
