NT Style Domains
Configure the HP CIFS Server as a BDC
Chapter 482
HP CIFS does not implement a true SAM database and nor its
replication. HP CIFS implementation of BDCs is very much like a PDC
with one important difference. A BDC is configured like a PDC except
the smb.conf parameter, domain master, must be set to no.
NOTE security: Set this parameter to user to ensure that Windows users,
client machine accounts, and passwords are stored and managed in the
smbpasswd file or LDAP backend.
domain master: Set this parameter to no in order for the HP CIFS
Server to act as a BDC.
domain logon: Set this parameter to yes to provide netlogon services.
Encrypt passwords: You set this parameter to yes, the passwords used
to authenticate users are encrypted. You must set this parameter to yes
when you configure HP CIFS Server to act as a BDC.
Promote a BDC to a PDC in a Samba Domain
If a PDC fails or needs to be taken out of services, simply set "domain
master = yes" on a BDC. It will then register the appropriate NetBIOS
names and will assume the PDC role.
