[Samba] Domain User problems

[G K]

I am using Samba 2.2.5 on RedHat 7.3.

Here's the setup:
I have my samba setup as PDC on a windows (Win9x)
network. I have encrypted passwords enabled with all
users in smbpasswd file. The linux server is running
NIS with all the same (samba) users in /etc/passwd &
NIS.

Here's the problem:
A user can login to the Domain fine AND their login
script executes. However, their home directory is not
visible and if I create a file in the tmp directory as
that user, the owner on the new file is nobody:nobody
for each user. So if I have a directory with 770
permissions, which I need to have, no user can access
that directory. (currently, all shares have guest ok
set to yes)

What is happening that the user is changing to nobody?

Thanks...
