Hi
I am having problems logging into a Windows 2000 client in a samba domain.
I have added a root account using smbpasswd -a, a machine account to
/etc/passwd with a $ appended to the end and home space and shell set to
/dev/null and /bin/false.
Then I added this machine to smbpasswd with smbpasswd -a -m machine_name.
Having done this I restarted samba and logged into windows. I changed from a
workgroup to the relevant domain and after about two minutes of egg-timer I
got a message welcome to the test4 domain - you must reboot for changes to
take effect etc.
After I rebooted I tried to logon to the domain using the root account I had
setup. I got an error message saying that the computer account did not exist
on the domain etc that other people have posted about.
At this point I figured that at no point had I told windows what password to
use when authenticating itself to the domain so I ran smbpasswd -n
machine_name$ to set the computer password to null and then allowed (against
better judgement) null passwords in smb.conf.
I rebooted windows and tried to login to the domain the same as before with
the result that I was told you cannot login to the test4 domain now because
it is not available. I checked with tcpdump and network connectivity is
*not* the problem.
If I log into the pc with a local account I can browse the domain in
net'hood and I can map a network drive passing over one of the usernames eg
root that I have setup.
I have tried this several different times using different domain names and
different client account names. All with the same result.
I have read through the faqs, how-tos etc and months worth of list messages
but can't find an answer to this particular problem.
Can anyone help please?
Here is my smb.conf
[global]
workgroup = TEST4
server string = test4
encrypt passwords = Yes
update encrypted = Yes
null passwords = Yes # I'd rather not have this
username map = /map # /map says root = root. This does not appear to
help/make any diff
unix password sync = Yes
log level = 3
log file = /var/log/samba/log.%m
large readwrite = Yes
time server = Yes
domain admin group = root @wheel
add user script = /usr/sbin/adduser %m
domain logons = Yes
os level = 255
preferred master = True
domain master = True
wins support = Yes
admin users = root
hosts allow = 192.168.0.
[homes]
username = %S
read only = No
only user = Yes
[netlogon]
path = /tmp/netlogon/
read only = No
This is only a test machine so I'm not bothered about shares and printers
and stuff. I just want the pdc emulation to work so I know what to do on the
real server which is currenlty only supporting a workgroup.
Other details
Windows version: 2000 Professional sp2 (all recent patches installed)
Server: Red Hat 7.2 kernel 2.4.7-10
samba 2.2.2 (but I had the same problems with 2.2.1a supplied out of the can
with Red Hat - yes I did remove 2.2.1a before installing 2.2.2)
Many thanks
