hi, what is the following sentence from "WHATS NEW IN Samba 3.0 alpha21" means: -------------------- Active Directory support. This release is able to join a ADS realm as a member server and authenticate users using LDAP/kerberos. -------------------- what I would like to do is a samba as domain contorller (PDC for win9x and domain contorller w2k professional sp3) but there is also a few w2k server. is it possible to use samba with ldap as domain contorller? (like an AC if I run w2k server? or what kind of features can't be used when I use samba with ldap as domain contorller? do I need samba 3.0 or can I do it with 2.2.7? thank you for your help in advance. yours.
