Hi ! I struggle for the last month or so (part time of course) to connect my local samba server (to be a file server) to an Open Directory (Mac OS X) master, it's samba part is configure as a PDC. So, my samba server is a linux (RHEL/CentOS 6), version 3.5.4.68.el6_0.2 on a local net composed of a mixture of Windows (from XP to 7), macs and linux. Those a our workstation. The OD Master is at a different site, on a different subnet, but accessible via a point to point connection. So, the only way I found to be able to autheticate to the OD users are as follow : [global] workgroup = cybercatwg server string = Hamel2 netbios name = HAMEL2 security = domain password server = odmaster encrypt passwords = yes wins server = 192.168.110.251 192.168.110.251 is my OD master. Our localnet is 192.168.7.0/24. I did have to do : net join -S odmaster -U diradmin to join the odmaster domain on the linux file server. Now, with this, on my local linux server, I can do : smbclient -U oduser -L //192.168.7.45 and enter that user password, and get a list of the shares. But from any other computer on my localnet, I just get a wrong password, NT_STATUS_LOGON_FAILURE or other. My logs don't say anything out of the ordinary... Can any one give me some direction as where to look ? Regards,
