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.
...
Those are following the following grammar (from RFC 4512 ) :
Code Blocknoformat |
---|
<SyntaxDescription> ::= <LPAREN> <WSP> <numericoid> ( <SP> "DESC" <SP> <qdstring> )? <extensions> <WSP> <RPAREN> |
Only one is already defined: in http://www.rfc-archive.org/getrfc.php?rfc=4517
34 of them are defined in RFC 4517. For instance, here the definition of Boolean syntax :
No Formatcode |
---|
3.3.3. Boolean A value of the Boolean syntax is one of the Boolean values, true or false. The LDAP-specific encoding of a value of this syntax is defined by the following ABNF: Boolean = "TRUE" / "FALSE" The LDAP definition for the Boolean syntax is: ( 1.3.6.1.4.1.1466.115.121.1.7 DESC 'Boolean' ) This syntax corresponds to the BOOLEAN ASN.1 type from [ASN.1]. |
They Here are the new one we need to implement the MetaSchema, described in the following table :
Desc | OID | Extensions | rules | nameOrNumericId | 1.3.6.1.4.1.18060.0.4.0.0.0 | - | Must be a valid Name or a valid OID |
---|---|---|---|---|---|---|---|
objectClassType | 1.3.6.1.4.1.18060.0.4.0.0.1 | - | Should be one of those 3 strings :
| ||||
numericOid oid | 1.3.6.1.4.1.18060.0.4.0.0.2 | - | Must be a valid numeric OID | ||||
usage attributeTypeUsage | 1.3.6.1.4.1.18060.0.4.0.0.3 | - | Should be one of those 4 strings :
|
MatchingRules
The Matching rules are deifned in RFC 4512 :
number | 1.3.6.1.4.1.18060.0.4.0.0.4 | - | Must be a number |
oidLen | 1.3.6.1.4.1.18060.0.4.0.0.5 | - | Must be a valid numeric oid followed |
objectName | 1.3.6.1.4.1.18060.0.4.0.0.6 | - | Must be a valid name a-zA-Z(a-zA-Z0-9-;)* |
MatchingRules
The Matching rules are defined in RFC 4512 :
No Format |
---|
<MatchingRuleDescription> ::= <LPAREN> <WSP>
<numericoid> <MRParameters>
|
Code Block |
<MatchingRuleDescription> ::= <LPAREN> <WSP> <numericoid> <MRParameters> <SP> "SYNTAX" <SP> <numericoid> <extensions> <WSP> <RPAREN> <MRParameters> ::= ( <SP> "NAME" <SP> <qdstrings> | <SP> "DESC" <SP> <qdstring> | <SP> "OBSOLETESYNTAX" <SP> )+ |
Here are the new MatchingRules :
<numericoid>
<extensions> <WSP> <RPAREN>
<MRParameters> ::=
( <SP> "NAME" <SP> <qdstrings> |
<SP> "DESC" <SP> <qdstring> |
<SP> "OBSOLETE" )+
|
Here are the new MatchingRules :
Name | OID | Desc | Obsolete | Syntax | Extensions |
---|---|---|---|---|---|
OidMatch | 1.3.6. | ||||
Name | OID | Desc | Obsolete | Syntax | Extensions |
OidMatch | 1.3.6.1.4.1.18060.1.1.0.2.1 | Match an OID | no | OID | - |
BooleanMatch | 1.3.6.1.4.1.18060.1.1.0.2.2 | Match a Boolean | no | Boolean | - |
NameOrOidMatch | 1.3.6.1.4.1.18060.1.1.0.2.3 | Match a name or an OID | no | NameOrOid | - |
TypeMatch | 1.3.6.1.4.1.18060.1.1.0.2.4 | Match a type of ObjectClass | no | Type | - |
UsageMatch | 1.3.6.1.4.1.18060.1.1.0.2.5 | Match an attributeType Usage | no | Usage | - |
...
The ObjectClass element is described in RFC 4512 :
Code Blocknoformat |
---|
<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 :

Ordering is useless, so is Substr.
