Hi, I'm running Ubuntu 12.04 server with Samba4 setup as a DomainController - following the OpenChange Cookbook. Everything works, except for file shares not using the user's group. All users view via smbstatus -v show group 'users' no matter what AD group they are in. I've also setup the box to use LDAP authentication using nslcd via nsswitch.conf and using kerberos, but it doesn't matter what, the smbstatus shows group 'users' (gid=100) for all users. Here's my smb.conf: Code: cat /usr/local/samba/etc/smb.conf # Global parameters [global] ### Configuration required by OpenChange server ### dcerpc endpoint servers = +epmapper, +mapiproxy dcerpc_mapiproxy:server = true dcerpc_mapiproxy:interfaces = exchange_emsmdb, exchange_nsp, exchange_ds_rfr ### Configuration required by OpenChange server ### workgroup = SFPI-TEST realm = SFPI-TEST.local netbios name = OPENCHANGEDEV server role = active directory domain controller server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate [netlogon] path = /usr/local/samba/var/locks/sysvol/sfpi-test.local/scripts read only = No [sysvol] path = /usr/local/samba/var/locks/sysvol read only = No [Homes] path = /var/openchange/users/%U read only = no [IT] path = /var/openchange/IT preserve case = yes browseable = yes read only = no hide special files = yes valid users = DanteBell,KateL [Profiles] path = /var/openchange/Profiles read only = no Connection using smbclient: Code: smbclient -d3 -U DanteBell%PASSWORD -W SFPI-TEST //192.168.4.110/IT lp_load_ex: refreshing parameters Initialising global parameters rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) params.c:pm_process() - Processing configuration file "/etc/samba/smb.conf" Processing section "[global]" added interface eth0 ip=fe80::de0e:a1ff:fe93:7b12%eth0 bcast=fe80::ffff:ffff:ffff:ffff%eth0 netmask=ffff:ffff:ffff:ffff:: added interface eth0 ip=192.168.4.222 bcast=192.168.7.255 netmask=255.255.252.0 Client started (version 3.6.3).

I've also verified using wbinfo sid-to-group,etc and that all looks OK.
