samba - Aug 2005 - mount.cifs and UID mapping

Hi!

I have mounted samba disk with mount.cifs (smbmount has problems with
codepage [Czech] - I can't use it). How do I map the server UID/GID to
client UID/GID? (I can't have the same UIDs/GIDs on all computers.)
Classic mount parameters uid/gid can't be used if "CIFS Unix
extensions"
are used on Samba server.
Google has not answered my questions (maybe I asked wrong).

Thanks, pf
