Add 'memberOf' attribute to ApacheDS

Question

I am trying to simulate Active Directory's memberOf attribute in Apache Directory. I have added the following entry for memberOf to my LDIF file:

dn: m-oid=1.3.6.1.4.1.18060.0.4.3.2.1,ou=attributeTypes,cn=other,ou=schema
m-usage: USER_APPLICATIONS
m-equality: distinguishedNameMatch
objectClass: metaAttributeType
objectClass: metaTop
objectClass: top
m-name: memberOf
m-oid: 1.3.6.1.4.1.18060.0.4.3.2.1
m-obsolete: FALSE
m-noUserModification: FALSE
m-syntax: 1.3.6.1.4.1.1466.115.121.1.27

When I start ApacheDS the following warning is logged:

   WARN  [ContainerBackgroundProcessor[StandardEngine[Catalina]]] entry.ServerStringValue - Cannot normalize the value :Encountered name based id of memberOf which was not found in the OID registry

This causes problems later on because my application tries to user the memberOf attribute as a search filter.

Is anything wrong with the way I specified the LDIF entry?
