Samba access without a UNIX user account

[| anson chi |]

Hello All,

I have a very simple question which I may already know the answer to:

I was wondering if there is any possible way for a Windows user to have Samba access without creating a new UNIX user account for them. My thought is no. But I wanted to double check.

To anyone, please let me know. Thank you all and have a great day.
