NFS and Kerberos

Hi, Does anybody work on the implementation of Kerberos "security" in Linux's NFS (http://www.faqs.org/rfcs/rfc2623.html)? I don't need it right now, I've just noticed Kerberos is becoming mentioned in Solaris documentation so it may be handy in mixed Linux - Solaris environments. -- Alexandr.Malusek@imv.liu.se
