Well, I promised to make a draft for a LDAP class library but I did
not have the time. It's still in my mind to write something like
this because it would make some parts of web2ldap much cleaner.

Such a class library should contain classes for syntaxes,
attributes, objectclasses and whole entries. E.g. take a look at the
schema configuration files coming with OpenLDAP 2.0. You'll find
things like

----------------- snip -------------------
objectClass: ( 1.3.6.1.4.1.4203.666.3.3 NAME 'OpenLDAPorg'
        DESC 'OpenLDAP Organizational Object'
        SUP pilotOrganization 
        MAY ( authPassword $ displayName $ labeledURI ) )

attributetype ( 0.9.2342.19200300.100.1.2 NAME
'textEncodedORAddress'
        EQUALITY caseIgnoreMatch
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )
----------------- snip -------------------

which gives a pretty good idea of what is need as attributes in a
objectClass object or attribute object. These things should all be
indexed/referenced by the unique, numerical OID.

Hmm, I could not find syntax definitions in OpenLDAP 2.0 alpha4 but
you can query LDAPv3 servers for their locally-defined schema. I
attached the schema of ldap.surfnet.nl in LDIF which might give you
a rough idea of the whole thing.

Ciao, Michael.
