Backup Domain Controller (BDC)
HP CIFS Server A.02.01 provides the BDC features and supports BDCs
in a domain in which it acts as a PDC. 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
security and network integrity.
• The BDC on a local segment can handle logon requests and
authenticate users while the PDC is very busy. It can help to add
robustness to network services.
• A 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.
NOTE HP CIFS Server can only function as a BDC to an HP CIFS PDC.
NOTE HP CIFS BDC does not support replication to a PDC. Running a Samba
3.0 BDC with a non-LDAP backend can have difficulty in synchronizing
the SAM database.
For detailed information on how to set up and configure an HP CIFS
Server as a BDC, refer to Chapter 5, “Backup Domain Controller
Support”, in the HP CIFS Server A.02.01 Administrator’s Guide.
