Samba password issue

[Neil.Newman]

Is it possible to have the users password on the Unix end to be
different to that of the Windows client user.

Example:
I have a Windows 2000 user who logs onto his PC as "fredblogs" with a
password of "password1".
On the Unix Samba end I have the user "fredblogs" setup with a password
of "password2".

I am then unable to access the Unix server, if I reset the Unix users
password to "password1" he is able to access the server, any suggestions
would be great.
