My goal is to make our users can access their own workstation account and
personal files from windows XP/7.
So, it seems to me that if I can setup a samba server and let users login
from windows using NIS authentication,
that would be perfect, then I don't need to create smb accounts again.
The only thing a user needs to do is to explore the link such as
\\testcad16\<user_account>, then one can access his own
workstation account and files.

In such case, how should I do to achieve my goal?
I've been tried many samba versions, and each version seems to have mild
difference while setting smb.conf.
some parameters work and some don't for one version, but maybe stands in
opposite for another.
I am kind of confused which parameters are what I need.

Here is my smb.conf (not from testparm), I removed comments and disabled
I did remove those lines you suggested,

        workgroup = SMBTEST
        server string = Samba Server Version %v
        netbios name = testcad16
        hosts allow = 127. 172.26.
        dns proxy = no

        load printers = yes
        cups options = raw

        comment = Home Directories
        browseable = no
        writable = yes
;       valid users = %S
;       valid users = MYDOMAIN\%S

        comment = All Printers
        path = /var/spool/samba
        browseable = no
        guest ok = no
        writable = no
        printable = yes

and I tried some test as below
