samba - Nov 2001 - win 95/98 configuration

Hello:

I need to install a samba server, this server will have a shared directory
named "comun", my clients are going to be win 95 and win98 boxes but
their
names don?t match with users names. for example: the winbox  is
"proc1" and
his users are "ajimenez" and "dbenitez". in addition, I
can?t change the
machine?s name neither the users names. how to validate the users?

thanks for your help
