[Samba] samba 3.0.7 cannot join NT4 domain

I looked into the docs and searched thru the Net.

Googling for "NT_STATUS_PIPE_NOT_AVAILABLE"
yields rather large list of questions about
this situatins, but no working hints so far.

I believe my samba installation is done very carefully
(entirely unlike "grab rpm and be happy" style)
and I can try to find out what's going on.

Let me describe what do I have so far:

My samba is built from sources and is laid out as follows:

/usr/app/samba-4.0.7/{bin,include,lib,man,sbin,swat}
	these files never change in normal
	samba operations and on reconfiguration/experiments

/usr/app/samba-4.0.7/var/{etc,lock,log,pid,private}
	this is the "dynamic" data, configs, etc

/lib/security/pam_winbind.so -> /app/samba-3.0.7/lib/pam_winbind.so
/lib/libnss_winbind.so ->       /app/samba-3.0.7/lib/libnss_winbind.so
/lib/libnss_winbind.so.2 ->     /app/samba-3.0.7/lib/libnss_winbind.so.2
/lib/libnss_wins.so ->          /app/samba-3.0.7/lib/libnss_wins.so
/lib/libnss_wins.so.2 ->        /app/samba-3.0.7/lib/libnss_wins.so.2
	symlinks to needed DSOs

/var/service/{smb_n,smb_s,smb_w}
	daemontools-controlled 'services' which start
	nmbd, smbd and winbindd, respectively. Like this
	(all three daemons are started with these options):
	#!/bin/sh
	exec 2>&1
	exec </dev/null
	echo "* Starting"
	exec env - winbindd --stdout --foreground --interactive

/etc/nsswitch:
...
passwd:         compat winbind
group:          compat winbind
hosts:          files wins dns
...

I plan to use sshd as one of ways to test NT auth, so:
/etc/pam.d/sshd:
auth            required        pam_unix_auth.so
auth            sufficient      pam_winbind.so use_first_pass use_authtok
account         sufficient      pam_winbind.so user_first_pass use_authtok
password        required        pam_unix_passwd.so
password        sufficient      pam_winbind.so use_first_pass use_authtok
session         required        pam_unix_session.so
session         required        pam_mkhomedir.so
session         sufficient      pam_winbind.so use_first_pass use_authtok

smb.conf - see below.

I need to run this server as NT4 domain member.
I start from completely clean state (var/lock and
var/private are empty).	I start the daemons:

# cd /var/service; svc -u smb*
(this is daemontools way of starting 'services')

nmbd and smbd are working fine and I will not go into
details like their log contents. Let's concentrate on winbindd.
Apparently it tries to connect to PDC:

At this point, NT Server Manager shows HUNTER is the list of
computers as:

Computer   Type                   Description
---------- ---------------------- ------------
HUNTER     Windows NT 4.9 Server  Samba 3.0.7

Which is a bit strange because I did not join domain yet.
(It isn't listed if I uncheck View->Show Domain Members only)

According to swat/help/Samba-Guide/unixclients.html#ch9-nsswbnd,
I shall join the domain: net rpc join -U user%pass.

Shall I do it while daemons are running or not?
Shall I do "Computer->Add to Domain" in NT Server Manager before this?
Docs does not answer these.

Oh, well. Will try to do it with running daemons and without 
doing that thing to NT Server Manager.

# net rpc join -U vda%XXXXXXXXXXXXXXX
Joined domain PORT.

Looks good? Not so. wbinfo -u fails with this in winbindd log:

2004-09-22 16:45:33.558053500 rpc: trusted_domains

2004-09-22 16:46:27.866979500 [ 6853]: list users

Let's see what will happen if I restart daemons:

# svc -d smb*; sleep 5; svc -u smb*

Winbindd log:

Not good. Okay. Let's try to pre-join HUNTER in NT ServMan first.

Stopping daemos. (Daemons forget to remove their pidfiles from var/pid/*.
Oh well.) Purging everything in var/{lock,private}, deleting HUNTER
from domain via ServMan. (HUNTER remains for 15 mins. Oh well #2.
hostname hunter2 will hopefully work around that :)

Pre-joining HUNTER2 in NT ServMan. Starting daemons.

# net rpc join -U vda%XXXXXXXXXXXXXXX
Joined domain PORT.
# wbinfo -u
Error looking up domain users

Basically same info in all logs.

Looks like my samba is unable to convince PDC that it is
indeed a member of the domain.

Any helpful hints?
