Problem with NT4 and passwords

[Graham Alston]

Hi all,

My first posting as a Samba newbie!

I have Samba 1.9.18p5 serving on Redhat Linux 5.1 on a machine called
Linus. My problem is that some of my NT4 PC users cannot access their
autohome directories. After typing in their name and password NT reports
"\\Linus\joe is not accessible. The account is not authorized to login
from this machine."
Their Linux and NT usernames and passwords are the same.
This problem only occurs with some users and not others.

Here is my smb.conf file:

[global]
   workgroup = USERS
   comment = RedHat Samba Server
   volume = RedHat4

   printing = bsd
   printcap name = /etc/printcap
   load printers = yes

   log file = /var/log/samba-log.%m
   max log size = 50

   short preserve case = yes
   preserve case = yes

   lock directory = /var/lock/samba
   locking = yes
   strict locking = no
   share modes = yes
   security = share
   socket options = TCP_NODELAY 

[homes]
   comment = Your Home Directory
   writable = yes
   browseable = no
   read only = no
   preserve case = yes
   short preserve case = yes
   create mode = 0750

[printers]
   comment = All Printers
   path = /var/spool/samba
   browseable = no
   printable = yes
   public = no
   writable = no
   create mode = 0700

[sales_market]
   comment = Sales and Marketing Directory
   path = /market
   public = yes
   only guest = yes
   writable = yes
   printable = no

[admin]
   comment = Administration Directory
   path = /admin
   public = yes
   only guest = yes
   writable = yes
   printable = no

Any help would be greatly appreciated.
Graham
