Introduction

HP CIFS Server version A.02.01 provides the following enhancements to

support BDCs in a domain in which it serves as a Primary Domain

Controller (PDC):

• The ability to act as a BDC to an HP CIFS Server PDC

• The ability to act as a BDC for Windows clients including Windows

NT, XP, SP2 and Windows 200x

• Support for Windows NT logon scripts

• View resources on a Samba BDC using the Microsoft Server

Manager for Domain tool

• Support for local and roaming proﬁles

• Support for the speciﬁed logon home share to a Samba server

Advantages of Backup Domain Controllers

HP CIFS Server with BDC support provides the following beneﬁts to the

customer:

• The BDC can authenticate user logons for users and workstations

that are members of the domain when the wide area network link to

a PDC is down. A BDC plays an important role in both domain

seurity and network integrity.

• The BDC can pick up network logon requests and authenticate users

while the PDC is very busy on the local network. It can help to add

robustnees to network services.

• The BDC can be promoted to a PDC if the PDC needs to be taken out

of services or fails. This is an important feature of domain controller

management. To promote a BDC to a PDC on the HP CIFS Server,

change the domain master parameter from "no" to "yes".

Limitations

The following is a list of limitations for the BDC support:

• HP CIFS Server can only function as a BDC to an HP CIFS PDC.
