> The constructor in DefaultSchemaLoader has the following comment:
> {code}
>   // TODO Handle schema loading on other LDAP servers
> {code}
> For OpenLDAP this would require searching subtree under cn=schema,cn=config and handling attributes like:
> {code}
>   olcAttributeTypes: {1}( 2.5.4.4 NAME ( 'sn' 'surname' ) DESC 'RFC2256: last (family) name(s) for which the entity is known by' SUP name )
>   olcObjectClasses: {4}( 2.5.6.6 NAME 'person' DESC 'RFC2256: a person' SUP top STRUCTURAL MUST ( sn $ cn ) MAY ( userPassword $ telephoneNumber $ seeAlso $ description ) )
> {code}
> Note that there is also an 'olcObjectIdentifier' attribute type that seems to be used to create macros for interpolation in OID's used in other attributes:
> {code}
>   olcObjectIdentifier: OLcfg 1.3.6.1.4.1.4203.1.12.2
>   olcObjectIdentifier: OLcfgAt OLcfg:3
>   olcObjectIdentifier: OLcfgOvAt OLcfgAt:3
>   olcObjectIdentifier: OMsyn 1.3.6.1.4.1.1466.115.121.1
>   olcObjectIdentifier: OMsBoolean OMsyn:7
>   olcAttributeTypes: ( OLcfgOvAt:10.4 NAME 'olcUniqueStrict' DESC 'Enforce uniqueness of null values' EQUALITY booleanMatch SYNTAX OMsBoolean SINGLE-VALUE )
> {code}
> However this additional complexity seems to only be used for the internal/vendor-specific schema itself (not 'core', 'nis', etc.).
> Attached is LDIF output of from searching {{cn=schema,cn=config}}.
