A few question regarding schema
Hello,
Before I begin let me butter you guys up by saying that the ldapbis
documents are sooo much easier to read then the original RFC's. You're
doing a great job at de-mystifying LDAP. Thanks.
I have a few question after reading [MODELS] and thought I can post them
here. If this is not the approapriate list I appologize.
1). Most schema entities/objects have the option of being flagged as
OBSOLETE. I say most because Syntax is the only exception to the rule.
I'm trying to figure out why this is. Is it because Syntaxes are always
active once defined? Meaning it makes no sense to mark them as
inactive? If so what happens if a server decides not to support a
Syntax and needs to deprecate it before removing the Syntax?
2). Also as a general rule, most schema objects have a unique OID
assigned to them. The only exception to this rule are
matchingRuleUses. For these entities the numericoid is the OID of the
matchingRule they are associated with. So the question arises: What
then is the cardinality between matchingRules and their
matchingRuleUse[s]? I'm guessing that its zero or one matchingRuleUse
per matchingRule because you can reference multiple attributes for which
the matchingRuleUse would apply to. Hence it would be redundant to have
a many to one relationship.
3). I'm trying to find more information on schema extensions as in:
SyntaxDescription = LPAREN WSP
numericoid ; object identifier
[ SP "DESC" SP qdstring ] ; description
/---->extensions WSP RPAREN ; extensions
|
* these extension right here
Could you point me to some detailed information on this subject?
Thanks much,
Alex Karasulu
