samba - Sep 2004 - Redhat, Samba 4, Kerberos, Netscape Directory Server

As you may have heard Redhat just recently acquired Netscape's Directory 
Server.  I am curious about any potential compatibility issues that we 
may run into down the road with Samba 4.  In particular can any 
integration be done with Netscapes LDAP and are we going to be facing 
any major issues if we remain on MIT kerberos?

Any thoughts/feedback would be greatly appreciated.
