No local LDAP server was located (tried openldap v2/v1, umich-ldap).
If you wish to use sendmail and LDAP, you'll need to make sure your
server has the requisite schema setup.
You can find the schema (old and new) in the following places:
* $SCHEMA_PATH/sendmail.schema for the version of LDAP you
currently have installed (if any)
* /usr/share/sendmail/examples/ldap/sendmail.schema.<v>
where <v> is
<v1> for older schema (sendmail.{o,a}t.conf) format
<v2> for newer schema (sendmail.schema) format
If you later install a local LDAP server, be sure to re-run $0.
EOT
elif [ $FOUND -eq 1 ] && [ $NEW -eq 1 ]; then
cat <<-EOT
You have a local $LDAP_VERSION server! Depending upon how (and if)
you wish to use LDAP with sendmail, you'll want to check your
slapd.conf file and possibly include these files:
* $SCHEMA_PATH/sendmail.schema <- alias and other map support
* $SCHEMA_PATH/misc.schema <- OpenLDAP V2 ldap-mail-routing
If you later change your local LDAP server, be sure to re-run $0.
