problem with samba on a NT domain

[Remy Bruno]

Hi
I sent a message few days ago about the problems I had to connect from
my linux-samba box to a win95 box.
I downloaded the latest version of samba (2.0.0-alpha13), put
"security=domain" in smb.conf and now, smbclient works!
But smbmount still doesn't work and smbpasswd -j (to "join" the
workgroup, I read of it in
http://gd.tuwien.ac.at/samba/ntdom_faq/page6.html) doesn't work either
and reports:

(...)
Connecting to 160.228.92.5 at port 139
cli_net_auth2: Error NT_STATUS_NO_TRUST_SAM_ACCOUNT
cli_nt_setup_creds: auth2 challenge failed
modify_trust_password: unable to setup the PDC credentials to machine
REZO. Error was : NT_STATUS_NO_TRUST_SAM_ACCOUNT.
1998/10/22 23:10:21 : change_trust_account_password: Failed to change
password for domain REZ.
smbpasswd: Unable to join domain REZ.

any ideas of what is wrong?

thanks
