sendmail+LDAP

[Catherine Hollnsteiner <cathy@ntsp.nec.co.jp>]

hello,

i'm trying to use openldap with sendmail for mail routing but when i run
openldap in configuration file processing mode (level 64)
these is the output:

/usr/etc/openldap-2.0.7/etc/openldap/schema/mail-routing.oc.conf: line
10: old attribute type format not supported.
line 11 (attribute mailHost            cis)
/usr/etc/openldap-2.0.7/etc/openldap/schema/mail-routing.oc.conf: line
11: old attribute type format not supported.
line 12 (attribute mailLocalAddress    cis)
/usr/etc/openldap-2.0.7/etc/openldap/schema/mail-routing.oc.conf: line
12: old attribute type format not supported.
line 20 (objectClass inetLocalMailRecipient
requires                      objectClass
allows                       mailLocalAddress,
mailRoutingAddress,                      mailHost)
/usr/etc/openldap-2.0.7/etc/openldap/schema/mail-routing.oc.conf: line

line 9 (index mailLocalAddress)
/usr/etc/openldap-2.0.7/etc/openldap/slapd.conf: line 9: unknown
directive "index" outside backend info and database definitions
(ignored)

i using the sendmail+LDAP howto as my reference, and i just noticed that
the version of ldap used/specified there is openldap-1.2.11.
me, i'm using openldap-2.0.7(as seen above). guess it's obviously not
being supported. can anyone tell me what to do to?
i really need this to work.
i really appreciate any help.
