Hi. Can anyone give me some help on migrating my Samba PDC from old hardware to a new box? Old hardware is running RedHat 9, with Samba 3.0.2a-1. New hardware is running Fedora Core 4 with Samba 3.0.14a-2. Old (fully working) PDC is using tdbsam backend for passwords. For simplicity, I'd like to do the same on the new one, although I could also move to LDAP it that's what's needed, though I only have about 50 users. Incidentally, the unix logins are looked after using NIS, and both servers are bound to the same NIS master, and it's working just fine. I'm having trouble finding a nice, clear set of instructions as to how to migrate samba tdbsam to LDAP, or tdbsam from one server to another. I tried setting up the new machine as a BDC (planning to promote it later), but it's not allowing any windows box to connect as anyone except root - just asks for username and password repeatedly. I did this from scratch by setting up the smb.conf file to say (with a few added comments): <snip> netbios name = charlotte workgroup = MY_DOMAIN_NAME server string = My New BDC (charlotte) passdb backend = tdbsam security = user # password server = antonia # This is the old PDC. Commented out right now. encrypt passwords = yes smb passwd file = /etc/samba/smbpasswd # Not used? local master = yes os level = 40 # OS Level is set to 60 on old PDC domain master = no # Want to make this a BDC first preferred master = yes domain logons = yes wins support = no # Tried this both as yes and no, no different. dns proxy = yes </snip> I then ran: net rpc getsid net rpc join -S antonia -w MU_DOMAIN_NAME -Uroot%MY_PASSWORD Both of these commands ran fine, giving the right answers. I then copied (using rsync) /etc/samba/passdb.tdb from the old PDC to the new box in the same place. Finally, (having checked with testparm) I started the smb service. It's fine, except that I'm unable to actually connect to the server from a windows workstation; it won't accept any username and password other than root, even although everything is in the same domain. Can somebody give me some pointers here? Thanks Paul.
