ObjectClass top

RFC 4512

objectclass ( 2.5.6.0
    NAME 'top'
    DESC 'top of the superclass chain'
    ABSTRACT
    MUST objectClass
)

Using MetaSchema

top is a very special ObjectClass, as it is the only one which can't be described with the MetaSchema, because top can't depend on itself because it can't exist before being created ! top will be hard wired in the server. Here is the LDIF file which could be used if we were to include it into the server :

dn: name=top,cn=metaSchema
objectclass: metaObjectClass
name: top
desc: top of the superclass chain
type: ABSTRACT
must: objectClass

ObjectClass alias

RFC 4512

objectclass ( 2.5.6.1
    NAME 'alias'
    DESC 'RFC2256: an alias'
    SUP top
    STRUCTURAL
    MUST aliasedObjectName
)

Using MetaSchema

dn: name=alias,cn=schema
objectclass: top
name: alias
desc: RFC2256: an alias
sup: top
type: STRUCTURAL
must: aliasedObjectName
