Dear colleagues,
I?m trying to replace an NT 4.0 PDC with a Samba 3 RedHat Enterprise
Server. Following some instructions on the web I get almost everything
(users, groups) using the "net vampire" command. The shares are
working
and it seems to be working fine.
The problem is when I shutdown the Windows PDC and promote the Samba
Server to "domain master = yes" because the computers cannot enter the
domain anymore, an windows error tells me that the domain controller is
busy or cannot be contacted. But if I enter the computer locally and try
lo see the network shares it works fine; the problem is with th logon
process.
Here is the global of the smb.conf
--------------------------------------------------------------------------
[global]
workgroup = RICANET
server string = Domain Controller - Samba %v
netbios name = COBB
# passdb backend = tdbsam
domain master = yes
domain logons = yes
local master = yes
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
unix password sync = yes
passwd program = /usr/bin/passwd '%u'
security = user
os level = 64
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
add user script = /usr/sbin/adduser -m '%u'
delete user script = /usr/sbin/userdel -r '%u'
add group script =/root/smbgrpadd.sh '%g'
delete group script = /usr/sbin/groupdel '%g'
add user to group script = /usr/sbin/usermod -G '%g' '%u'
add machine script = /usr/sbin/adduser -d /dev/null -s /bin/false -M
'%u'
admin users = dgonzalez administrator
wins support = yes
# idmap uid = 15000-20000
# idmap gid = 15000-20000
