Application to Core Schema

We will express the Core schema using the previously defined Ldap objects :

Country

The country ObjectClass in OpenLdap format :

Code Block

{code}

h1. Application to Core Schema

We will express the Core schema using the previously defined Ldap objects :

h2. Country

The country ObjectClass in OpenLdap format :
{code}
objectclass ( 2.5.6.2 NAME 'country'
    DESC 'RFC2256: a country'
    SUP top 
    STRUCTURAL
    MUST c
    MAY ( searchGuide $ description )
)
{code}
The Country ObjectClass using the MetaObjectClass definition will be inserted as an entry into the ou=schema partition. As it is declared in *core*, we use a DN which describe this relationship with the original filer :

...


{code
}
dn: name=country, dc=core, ou=schema
objectclass: MetaObjectClass
objectclass: MetaTop
objectClass: top
m-oid: 2.5.6.2
m-name: country
m-desc: RFC2256: a country
m-sup-objectClass: top
m-type-objectClass: STRUCTURAL
m-must: c
m-may: searchGuide
m-may: description
