No, this is not a requirement, as each site's 'PDC' can operate with reference to the central LDAP infrastructure, without netbios. > in fact, we just want singal sign on for every site when people travel > arround with their notebooks. > my concern is about machine account.i know client machine and server > keep a shared seceret. but i don't know if this seceret will > changing over time? or the seceret will keep staic? It changes over time, and the client will not contact the PDC to make that change.

These slaves will only need to contact the master on machine account change, adding machines etc. Andrew Bartlett -- Andrew Bartlett [EMAIL PROTECTED] Manager, Authentication Subsystems, Samba Team [EMAIL PROTECTED] Student Network Administrator, Hawker College [EMAIL PROTECTED] http://samba.org http://build.samba.org http://hawkerc.net
