I'm trying to get a samba server which is all by itself, No Windows DCs, or
even windows shares at all, to play nice with Linux clients.
The server is authenticating Win9x, NT and 2000 clients fine and dandy, and
now I have need to add linux clients to the scenario, and have dicovered an
issue I can't seem to work through. Perhaps someone can help?
On the linux client, I can login as a user that exists only on the samba
server (TEST+testuser) , except I get the following message:
id: cannot find name for group id 10000
When I do "wbinfo -t" I get back:
Secret is good.
When I do "wbinfo -u" I get back:
When I do "wbinfo -g" I get back:
When I do "getent passwd" I get:
cut for brevity
So far so good, until I do "getent group", which returns:
cut for brevity again
So my net groups "Domain Admins" and "Domain Users" don't show up when I
getent group, and there is no other network group that winbind can map to
gid 10000 when TEST+testuser logs in to the Linux client, and I suspect this
is why I get the ID message on login (?)
Once again, I am not using any Windows 9x, NT, 2000 servers, the Linux Samba
server is the only PDC (and the only DC).
Can anyone offer some help aside from the stuff that's around on the net.
It all seems to deal with using Samba in a Domain with an actual windows DC,
not as a standalone server being a DC.
I wonder why my client linux box can't see the domain groups on login, and
while I'm on the subject, where do "Domain Admins" and "Domain Users" come
from in the first place, and how do I add, delete or modify domain groups or
how do I make groups on the Linux Samba server display to linux clients?
Both server and Client use RedHat 7.3 (Stock Kernel) Samba wasn't installed
with the redhat setup, instead I downloaded the tarball for 2.2.5
I compiled the server software in the source directory with:
The server is set up as a PDC with an smb.conf file that looks like:
workgroup = TEST
netbios name = LINUXSRV
interfaces = 127.0.0.1 192.168.240.20
encrypt passwords = Yes
domain logons = Yes
os level = 64
preferred master = True
domain master = True
wins support = Yes
path = /home/%U
read only = No
browseable = No
path = /usr/local/samba/netlogon
browseable = No
I've configured the linux client and added it to the domain by:
Setting it's host name to linuxclient,
Compiling the samba software from source (2.2.5) in the source directory
Copied libnss_winbind.so to /lib
Created a link:
ln -s /lib/libnss_winbind.so /lib/libnss_winbind.so.2
copied pam_winbind.so to /lib/security
Created an smb.conf file for winbind that looks like
workgroup = TEST
winbind separator = +
winbind uid = 10000-20000
winbind gid = 10000-20000
winbind enum users = yes
winbind enum groups = yes
template homedir = /home/%U
template shell = /bin/bash
winbind use default domain = yes
wins server = 192.168.240.20
Created a init script to fire up winbind
edited /etc/nsswitch.conf to change the lines:
passwd: files winbind
group: files windbind
added these lines to /etc/pam.d/login:
auth sufficient /lib/security/pam_winbind.so
account sufficient /lib/security/pam_winbind.so
session required /lib/security/pam_mkhomedir.so skel=/etc/skel
did a: /sbin/ldconfig -v | grep winbind which returned:
libnss_winbind.so -> libnss_winbind.so
I started up the winbindd daemon on the client.
Then on the server, I did:
passwd -l linuxclient$
smbpasswd -a -m linuxclient
passwd -l testuser
smbpasswd -a testuser
On the linux client I did:
smbpasswd -j TEST -r 192.168.240.20
Which reported I joined the domain successfully.
Doing all this gets me the behaviour described above.
Any help will be appreciated!
