Configuring slapd.conf-less OpenLDAP

I'm trying to get OpenLDAP up and running on Fedora (12) using the cn=config-based configuration.

I've changed /etc/openldap/slapd.d/cn=config/oldCatabase={1}bdb.ldif to point to my domain:

olcSuffix: dc=endoframe,dc=net olcRootDN: cn=Manager,dc=endoframe,dc=net

And I've added:

olcRootPW: [slappasswd output]

However, I haven't had any luck using this password:

# ldapadd -x -D "cn=Manager,dc=endoframe,dc=net" -W -f Manager.ldif Enter LDAP Password: ldap_bind: Invalid credentials (49)

Is there some other way I should be specifying the password?
