This part "Unrecognized objectClass 'olcBdbConfig'" surprised me a bit,
as the line caused the problem is taken from openldap manual:

Quote from http://www.openldap.org/doc/admin24/slapdconf2.html

      5.2.6. BDB and HDB Database Directives

In addition to the olcDatabaseConfig objectClass, BDB and HDB database
entries must have the olcBdbConfig and olcHdbConfig objectClass,

Actually if you re-read that, you'll see that it says to use the 'olcBdbConfig' objectClass *in addition* to the olcDatabaseConfig objectClass.

However, adding files may work also...


Perhaps I missed some document, but what you said is not mentioned in
the document I referred to. I think it make a lot of sense to add new
database via LDAP, but a newbie would not be able to assume this can be
done, especially puzzled by not knowing what crediential should I use to
access db cn=config, because olcRootPW is not existing in any of the
ldif files except the one I just added:

# grep -R olcRootPW /etc/ldap/slapd.d/
\/etc/ldap/slapd.d/cn=config/olcDatabase=bdb:olcRootPW: secret
/etc/ldap/slapd.d/cn=config/olcDatabase={1}hdb:olcRootPW: secret

No, I recall that Ubuntu sets up some other form of authentication tied into the OS... I've never really got it though, so I can't help here. Maybe others on the list understand how this works by default on Ubuntu?
