[K12OSN] smbldap error message domain name related

[Krsnendu Dasa]

I copied my smbladp database over using slapadd.
It gave me this message. bdb_db_open:Warning - No DB_CONFIG file found
in directory /var/lib/ldap: (2)
Expect poor performance for suffix dc=harekrishna, dc=school,dc=nz

This domain name is the one I used on my previous server although it
is made up. That domain name exists on the internet, but does have any
thing ot do with this domain name.
I was not sure what to put for domain name so I put this.

Can you help me with this error message? What do I have to do now?
