Hi all, I've been struggling with this problem for quite some time, and I'm hoping someone will have an answer for me. I'm trying to use Samba to authenticate against a campus-wide NT domain setup. As such, I can't change any of the details of the NT domain. The NT domains are set up as follows: +-----> USER1 | MACHINES <-+-----> USER2 | +-----> USER3 Machines join the MACHINES domain, using a username (let's call it "addmachine") and password set aside for this purpose. USER1, USER2, and USER3 are trusted by MACHINES, and all user accounts are created in these three domains. I've got smbd and winbindd running under Samba 3.0.2a1. Issuing net join -S PDCNAME -Uaddmachine%password returns Joined domain MACHINES. Issuing wbinfo -m at this point will return: USER1 USER2 USER3 (MACHINES is absent.) Issuing wbinfo --sequence, however, returns: USER1 : DISCONNECTED USER2 : DISCONNECTED USER3 : DISCONNECTED MACHINES : 75917 Try as I might, I have never gotten Samba to connect to the USER1-3 domains. What am I doing wrong? The global section of my smb.conf (minus comments) is below. My apologies if this is a duplicate post; I tried posting it to linux.samba but that seems to just be a mail -> news gateway. Dan smb.conf: [global] workgroup = MACHINES server string = myservername log file = /var/log/samba/log.%m max log size = 50 security = domain password server = PDC encrypt passwords = yes socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 dns proxy = no winbind separator = + idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes
