[Gllug] Samba PDC

Thu Jun 17 13:10:31 UTC 2004

I am intending to replace our old windows NT domain controller with a 
samba version under Debian. User authentication is done with an ldap 
server on the same box. Thus far I have had a reasonable amount of 
success and my two test client (windows 98) are authenticating and 
picking up the policy file on the linux box, config.pol.

Thus far I cannot see any errors in my samba nor ldap logs when the 
machine logs in and all seems alright with the world. The problem is 
that neither 98 machine appears in Network Neighborhood, only the server 
is available. The windows 98 boxes are both setup for the correct 
workgroup/domain and are not appearing in the old domain. They can 
access each other via nbtstat and can browse each other's resources 
using \\machine-name.

I have attached my smb.conf file - any suggestions much appreciated.
Thanks,
Craig

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
    workgroup = testdomain
    netbios name = MACBETH
    host msdfs = yes
    interfaces = 172.16.1.99 127.0.0.1
    bind interfaces only = yes

# server string is the equivalent of the NT Description field
    server string = %h server (Samba %v)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
    wins support = yes

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#   wins server = 172.16.1.2

# If we receive WINS server info from DHCP, override the options above.
#   include = /etc/samba/dhcp.conf

# This will prevent nmbd to search for NetBIOS names through DNS.

# What naming service and in what order should we use to resolve host names
# to IP addresses

# that connects

# Put a capping on the size of the log files (in Kb).

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
;   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account

# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
