unix perm bits

[iddwb]

I'd like to use samba to share files among unix machines.  is there some
way to preserve all the unix permission bits across systems?  I notice the
execute bit is getting turned on by default on file creation.  Is this
becuase of the mapping of the execute bit to the archive bit?  Or do I
need a create mask entry to preserve these or is there something uniquely
unix?
