help! authentication again

[Maung, Than]

Hi all,

When I configure the SAMBA server with
password server = PDCNAME
security = server

I cannot access my shares if I don't have my user ID on the HP-UX box. When
I look at the log file, it was trying to connect me to the SAMBA server as
"guest" but not as my user ID. It will ask me for the user name and
password. When I type in the user name and password it will tell me that "
This user is not authorized to connect from this machine". This happens even
if I don't have SP 3 on my NT workstation. I also do not have hosts allow
and deny configured. It happens also on my Win 95 machine. If I have my user
name in my /etc/passwd file it will let me connect with a correct username.
Is my SAMBA server really checking my access against my NT domain
controller? I really need to have the ability to log in without having to
create user names on my SAMBA server. Is it a must that I have to use the
PAM routine? And if so can somebody give me some directions how to use it?
Or is there another way to do it?
The server is running HP-UX 10.20.

Thanks in advance

Than M Maung
