I know this does not really answer the question,
But the default Java LDAP JAAS supports it and it works like a charm

http://download.oracle.com/javase/6/docs/jre/api/security/jaas/spec/com/sun/security/auth/module/LdapLoginModule.html

I am assuming Glassfish's realm supports it as well.
perhaps specify the IP's as comma separated. Just a guess
