[vchkpw] Which files are involved in open-smtp?

[David Hubbard]

Hi all,
        can someone tell me what actually changes
when --enable-roaming-users is on?  Outside of the
creation of the clearopensmtp binary, is it just a
change to vchkpw that enables external programs to
have an IP added to open-smtp somehow when calling
it?

Thanks,

David
