Samba problems in an NT domain

[manish jain]

Hi,

I have a Linux box running Samba and participating in an NT-domain 
named ITGINDIA controlled by a PDC named "Server". I am unable to 
access Windows SMB shares from my machine despite providing a valid 
username and password to smbclient. Below is some sample output.


$ smbclient //server/common2all
added interface ip=192.168.10.13 bcast=192.168.10.255 
nmask=255.255.255.0
Got a positive name query response from 192.168.10.1 ( 192.168.10.1 )

2003 5.2]tree connect failed: NT_STATUS_ACCESS_DENIED

$ smbclient //server/common2all -U manishj
added interface ip=192.168.10.13 bcast=192.168.10.255 
nmask=255.255.255.0

$ smbclient //sachin/softwares -U manishj

$ smbclient //sachin/softwares
added interface ip=192.168.10.13 bcast=192.168.10.255 
nmask=255.255.255.0
Got a positive name query response from 192.168.10.12 ( 192.168.10.12 )
Password:
Anonymous login successful
Domain=[ITGINDIA] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]
tree connect failed: NT_STATUS_ACCESS_DENIED


Note that in the last case, the server identity reported is 'Windows 
2000 Lan Manager' whereas in the first 2 cases it is 'Windows 2003 
Server'.

Accessing my machine's SMB shares from Windows is possible but 
difficult. My SMB server shows up in the Network Neighbourhood, but 
clicking on it leads to a message amounting to 'Access denied'. To 
access any of my shares, Windows clients have to manually enter 
something like this in the address bar of Explorer :

							 
\\192.168.10.13\tmp

The client is then prompted for a username and password. But, despite 
setting my security in smb.conf to "domain" and the password server to 
the IP address of PDC, usernames and passwords valid in the NT-domain 
do not work. The only way to access my shares is to give the username 
as 'root' alongwith the matching password.

Attached is my smb.conf file, which allows password encryption.

Can someone please help me out ?
Thank you.
