Hi Joe,
Actually I think my terminology is a little off. From snooping around
a bit I think I want the attributeSchema information under
CN=Schema,CN=Configuration,DC=example,DC=com. What I was thinking of
originally are the "attribute syntax" definitions like:
( 2.5.18.3 NAME 'creatorsName' EQUALITY distinguishedNameMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.12
SINGLE-VALUE NO-USER-MODIFICATION USAGE directoryOperation )
But it's clear now that AD doesn't really use these textual definitions
(at least not anywhere I can see).
Anyway, the overall objective here is to do is to give my custom LDAP
client API intellegence (see previous post about scripting language
binding) about attributeSchema information so that the API can properly
type attribute values. In particular I need to create a table of at least
lDAPDisplayName, isSingleValued, and attributeSyntax. This table
will be consulted by the API to determine how to compare and present
values whether they be binary, multivalued, strings, etc.
To make it efficient I will need an index which will be just a hashmap
where the lDAPDisplayName is the key and the attributeSchema entry
is the datum. Additionally the attributeSyntax value should be one
of several predefined OID constants (e.g. ADSTYPE_CASE_IGNORE_STRING)
so that attributeSyntaxes can be comared logically.
Does any of this make sense? I suppose you don't get a little programmer
double talk here :-)
