OIM LDAP Connector: Provisioning of Custom Object Classes with Organizational Unit

Regarding chapter 9.12. in  https://docs.oracle.com/cd/E22999_01/doc.111/e28603/extnd_func.htm#BCGEDBCA_ custom object classes can be used. I exteded ouObjectClasses in Lookup.LDAP.OUD.Configuration. I used for the "Meaning:" in the lookup follwoing syntax: "top","organisationalUnit","myClass" Code is "ouObjectClasses. This is different to the documentation, but identical to the accountObjectClasses already present in the lookup. (tried also without quotation marks) Provisioning an Organisation via the GUI -> Manage  --> Organizations --> Provisioned Account --> +Provison selecting LDAP Organization Unit / IT Ressource / DN will provsion an OU into the OUD, but without my custom Class "myClass"
