Thread: Samba / Winbind / LDAP - Can't access shares




Samba / Winbind / LDAP - Can't access shares

2007-04-17 19:22:45
Hi All,

I have the following setup. Samba/LDAP PDC, Samba BDC, Samba
member 
server, Win2K member server, 300  Win XP Client PCs.

I can access the shares on the PDC from all  Win XP clients.
I can 
access the shares on the Win2K member server from all XP
clients, I 
can't however access any of the shares on the Samba BDC or
Samba member  
server from the XP clients.

LDAP is working fine and PAM/LDAP/NSS are working fine.
Getent  works 
for users and groups on all samba servers and net groupmap
list provides 
identical group mapping  across all samba servers. I can do
things like  
chmod  user."Domain Admins"  and it works. I can
use setfacl and 
generate acls with Domain groups in them and it works but I
cannot 
access the shares on the Samba servers from anywhere on the
network. 
wbinfo works on the samba member server but  cannot lookup
users and 
groups when run on the PDC and BDC.

OS's are Mandriva 2007 and Ubuntu Edgy. Samba version is
3.0.23d. All 
machines names are resolvable via nmblookup and nslookup and
I've been 
through every document and howto I can find as well as loads
of Google 
searches but have not managed to resolve it yet.

All help gratefully received. Cheers,

Jools
