[Samba] 3.0.7 net join to NT4 domain - silently fails?
I've got no responce to my mail with subject
'samba 3.0.7 cannot join NT4 domain', so I dug deeper.
I also read carefully these docs:
swat/help/Samba-HOWTO-Collection/domain-member.html
swat/help/Samba-HOWTO-Collection/winbind.html
This is what I observe:
1.I srtart from clean state:
PDC has no HUNTER machine account (chkd with L0phtcrack)
HUNTER has empty var/{lock,private}
samba daemons are stopped, logs are deleted.
2.I run:
# net join -U domadmin%password
Joined domain PORT.
l0phtcrack and SrvMgr show hunter$ now. (grayed out "WinNT wks or
server")
However, I have a msg in PDC security log (traslation from Russian):
"Session with computer HUNTER is not established, because this
computer has no trust record in SAM database."
AFAIK, this is bad. Joining the domain must store
machine trust record in PDC's SAM. PDC says it is not there.
Let's test winbindd anyway.
3.Starting winbindd. Log:

winbindd version 3.0.7 started.

Looks like step 2 'net join -U domadmin%password' does
not succeed despite saying 'Joined domain PORT'.
I think so because I have that security alert on PDC,
and winbindd have troubles. It is easily reproducible -
each net join attemtp produce one securily log message.
I cleaned up everything and reran 'net join' again with -d4.

What is "just_change_the_password: unable to setup creds
(NT_STATUS_NO_TRUST_SAM_ACCOUNT)!". Does this log ring a bell to anyone?
P.S. I grepped away timestamps. If you want them, unprocessed
output is below the sig. smb.conf is there too.
