supportedFeatures attribute?

[Ed Klavins <edvins.klavins@thenet.ch>]

Hi,

Just starting with ldap, after successfully building and installing
openldap 2.0.15.

Working on the simple 'getting started' examples, I've just
defined the simplest slapd.conf, but trying to start slapd (-d 1)
I get the following:

daemon_init: listen on ldap:///
daemon_init: 1 listeners to open...
ldap_url_parse_ext(ldap:///)
daemon: initialized ldap:///
daemon_init: 1 listeners opened
slapd init: initiated server.
slap_sasl_init: initialized!
No attribute "supportedFeatures" defined in schema
schema prep error
slapd shutdown: freeing system resources.
slapd stopped.

I've searched faqs, mailing lists, but couldn't find a
reference to supportedfeatures anywhere. 
Any idea on what I can try next?

thanks, ed

ps. my slapd.conf boils down to:

database        ldbm
suffix          "dc=example,dc=com"
rootdn          "cn=Manager,dc=example,dc=com"
rootpw          secret
directory       /var/openldap-ldbm
index   objectClass     eq
