Allow guest from an un-trusted domain

[Danny Travis]

I have a UNIX Samba server using an NT domain for authentication. I want
to allow a host in an un-trusted domain outside of the one my server is
in to be able to access a share as a guest. When that server tries to
map the guest share, samba tries to authenticate the un-trusted domain
and username to the domain that I am in and fails. Can I do this without
making the whole server security = share instead of security = domain
which is what I have now.

Thanks,
Danny Travis
