LDIF for moddn: "ldap_rename: Server is unwilling to perform (53)"

Hi!

Reading https://kb.symas.com/en_US/configuration/configure-delta-syncrepl I realized that my syncprov is on the original database, not on the accesslog. So I tried to fix it my "moving" the overlay like this:

dn: olcOverlay={0}syncprov,olcDatabase={0}config,cn=config changetype: moddn newrdn: olcOverlay={0}syncprov deleteoldrdn: 1 newsuperior: olcDatabase={3}mdb,cn=config

However as I got "ldap_rename: Server is unwilling to perform (53)" I wonder: Is my LDIF wrong, or is it an implementation restriction?

Do I have to restart the server with a fresh config?

Kind regards, Ulrich Windl
