Sendmail 8.10.0 has native LDAP support, using the LDAP schema described in the Internet RFC draft: http://www.iepg.org/docset/ids/draft-lachman-laser-ldap-mail-routing-01.txt Has anyone used openLDAP with this version of sendmail? If so, what schema did you use and do you have any translation tools for the same? regards, fletcher
