Introduction
We want to store the schema into ADS as any other entries. We have to define the minimum set of ObjectClasses an AttributeTypes needed to be able to bootstrap the schema.
ObjectClasses
The ObjectClass element is described in RFC 4512 :
<ObjectClassDescription> ::=
<LPAREN> <SP> <numericoid> <ocparameters> <extensions> <WSP> <RPAREN>
// Each parameters should not be seen more than once
<ocparameters> ::=
( <SP> "NAME" <SP> <qdescrs>
| <SP> "DESC" <SP> <qdstring>
| <SP> "OBSOLETE"
| <SP> "SUP" <SP> <oids>
| <SP> ( "ABSTRACT" | "STRUCTURAL" | "AUXILIARY" )
| <SP> "MUST" <SP> <oids>
| <SP> "MAY" <SP> <oids> )+
Here we have some elements which are already in the schema :
attributetype ( 2.5.4.0 NAME 'objectClass' DESC 'RFC2256: object classes of the entity' EQUALITY objectIdentifierMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 )
attributetype ( 2.5.4.13
NAME 'description'
DESC 'RFC2256: descriptive information'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{1024}
)
attributetype ( 2.5.4.41
NAME 'name'
DESC 'RFC2256: common supertype of name attributes'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{32768}
)
The other ones must be defined. Here is a table grouping all the missing elements :
