I see list discussions on this subject from a few years back but they
were very brief and, it seems, inconclusive.
I would be interested in hearing from anybody who has discovered the
"trick" to getting an EMC Celerra to join their Samba 3.x domain.
I have an old NetApp Filer happily joined. I simply created an account
with "smbldap-useradd -w filername" and when I then configured the
Filer
for CIFS it was immediately accessible and I could see
"SambaNTPassword"
and related bits in its record (LDAP backend using Fedora Directory
Services)".
I did the same for the EMC, "smbldap-useradd -w emcname". Then, when
I
create the EMC's CIFS server (with name, domain, NT4/netbios type, WINS
spec) it does appear in Domain browse list very quickly, but no
resources are available. The dump of the EMC's CIFS config (included
below) shows all of the correct Netbios stuff.
In LDAP, the SambaNTPassword attribute (and a few others created in
client records when a successful join is completed) are missing.
EMC documentation is to the effect "Windows NT servers are automatically
joined to a domain when created". This does not square with other joins
where a Samba root user/password are required. EMC does have a "Join"
option for its "server_cifs" command (that takes a password), but this
is supposedly only for Win2000+ . I tried it anyway. It times out.
When I start the EMC's CIFS service and run tcpdump with "host
emcname"
I see lots of bidirectional chat between the EMC and our PDC. I don't
see anything that indicates abject failure. I do see a regular
repetition of some NBT that seem like a join/registration attempt (see
below).
One thing that I do see are some occasional NBT broadcast messages that
I would not expect if the EMC was using WINS correctly, but it is
showing lots of unicast, so perhaps this doesn't mean much. In NBTSTAT,
the EMC shows up as an <00> and <20> (I assume those are the node
types
and that one of them is not "hybrid", which should be 08 IIRC)
One thought I just had was to chang the EMC's root password to match the
Samba admin/root in case somehow the "automatic" join is still
supplying
credentials using EMC's defaults.
In any event, if anyone has been there, done that, I would be interested
to hear from you.
Thanks,
Jim
