I set up Samba (2.2.3a) as a PDC Server and a Profiles Server for my 80 clients running Windows W2k Sp1 and W2k Sp2. If the profile for example is created with a Sp2 client and changes are made, after disconnecting and reconnecting with another Sp2 client the changes are correctly displayed. But if I modify with a Sp1 client a profile created with a Sp2 client, the profile will be damaged (i.e. further changes made with a Sp2 client will be ignored such as mail accounts or desktop wallpaper) and only changes made by sp1 client will be correcty applyed both for sp1 and sp2 clients! I use also smbuser file to map different users between Windows and Linux. Here is my smb.conf file (I think it is ok): [global] add user script = /usr/sbin/useradd -d /dev/null -g 100 -s /bin/false -M %u workgroup = BCCFILOTTRANO netbios name = FI0X07 server string = Linux PDC Server (%v) hosts allow = 10.113. 127. 10.112.1.182 printcap name = /etc/printcap load printers = no log file = /var/log/samba/log.%m max log size = 0 security = user encrypt passwords = yes smb passwd file = /etc/samba/smbpasswd username map = /etc/samba/smbusers socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 interfaces = eth0 eth1 local master = yes os level = 64 domain master = yes preferred master = yes domain logons = yes logon path = \\%L\profiles\%U logon drive = Z: logon home = \\%L\%U name resolve order = wins lmhosts bcast wins support = yes dns proxy = yes [homes] comment = Home Directories browseable = no writable = yes valid users = %S path = %H/NetDrive create mode = 0600 directory mode = 0700 [netlogon] comment = Network Logon Service path = /var/samba/netlogon guest ok = no browseable = no writable = no share modes = no [profiles] comment = NT Profiles path = /var/samba/ntprofiles create mode = 0600 directory mode = 0700 writable = yes browseable = no guest ok = no nt acl support = no # I tried yes/no but no difference
