OpenLDAP 2.1 and updatedn

hi,

while trying to add entry to an OpenLDAP server with ver 2.1.x, i faced an error:

no structural ObjectClass operational attribute

when removing the updatedn in the slapd.conf all works well.

i need the updatedn since the machine is part of a master - slave architecture.

to go around it i placed a "schemacheck" directive with the value "off"

it did not happen in the 2.0.x version of OpenLDAP.

I'm also using the core.schema provided with the server and my own custom schema, build with our OID

thanks in advance

eli
