I’m starting to manually migrate my samba3 (or now samba4 classic)
servers into a new samba4 AD domain. (All new servers are running with
v4.7.4.) The DCs are running fine and I’m testing my first member server.
Works well with Windows 10 domain members, but we won’t be adding all
clients into the domain just yet.
Our old login scripts that map the drives do create problems now, since the non domain members try to login with “LOCALCOMPUTERusername”, passwords are of course the same.
For my old samba 3 PDC, I successfully used
map untrusted to domain = yes to solve that problem. I’m now using the new default
will be the only value in 4.8 as far as I understand and it doesn’t seem
to work as I need it to. AFAIU the member server is supposed to delegate
the decision to the DC, which, in case it is unknown, should perform a
local authentication. I’m not sure what exactly “local” is (is it the AD
or the server?), but it doesn’t work here.
By default, and with map untrusted to domain = auto smbd will defer
the decision whether the domain name provided by the client is a valid
domain name to the Domain Controller (DC) of the domain it is a member
of, if it is not a DC. If the DC indicates that the domain portion is
unknown, then a local authentication is performed.
(man smb.conf v4.7.4)
So in short, is there an easy solution to map all unknown domains to
BSSuser? Since I don’t have more than this one domain, I don’t even
mind mapping everything.
DC smb.conf is fairly standard (left out netlogon/sysvol):
[global] workgroup = BSS realm = BSS.FQDN.EXAMPLE.COM netbios name = BARVA server role = active directory domain controller dns forwarder = 188.8.131.52 idmap_ldb:use rfc2307 = yes time server = yes
Member (file) server, left out the share definitions:
[global] workgroup = BSS realm = BSS.FQDN.EXAMPLE.COM security = ADS winbind enum users = yes winbind enum groups = yes winbind use default domain = yes winbind refresh tickets = yes winbind nss info = template template shell = /bin/false template homedir = /srv/samba/homes/%U # https://wiki.samba.org/index.php/Idmap_config_rid#Planning_the_ID_Ranges # Default idmap config for local BUILTIN accounts and groups idmap config * : backend = tdb idmap config * : range = 3000-7999 # idmap config for the domain idmap config BSS : backend = rid idmap config BSS : range = 10000-999999 store dos attributes = yes vfs objects = acl_xattr inherit acls = yes map acl inherit = yes
Thanks in advance,
