I'm trying to make the filesystems browsable from Windows XP, while maintaining correct UID/GID info. It seems this would be really simple, just let the user login to \\linuxmachine with his/her linux username & password, and everything they do happens as them. As you know - no such thing. :-(

This will work if samba is setup as PDC.
Add the NIS user to samba with smbpasswd -a <username>. Setup the passwd
passwd program = /root/newpasswd %u
/usr/bin/make -f Makefile.passwd
/var/yp/Makefile.passwd is just /var/yp/Makefile edited to only update
A password change from Windows will now update both databases. But then
there's the hassle of asking users for their existing NIS password so
you can add it to smbpasswd. Instead, just set it to <some_win_passwd>,
have the user login to Windows with <some_win_passwd>, password change
from Windows will then sync both databases to the same new password.
