In my setup of an app I want to use Kerberos in auth the authenticator in my login-config.xml. The app already used a Kerberos module named "com.sun.security.auth.module.Krb5LoginModule". I see other references to using this login module in the config but when I try I get: 2007-05-16 12:17:39,824 ERROR [STDERR] javax.security.auth.login.LoginException: unable to find LoginModule class: com.sun.security.auth.module.Krb5LoginModule Why?
