Hi David,
depends on what you mean - either there's a supported way
on how to extend the schema (pretty sure implementing the schema extensions via
LDIF is supported), however if you are talking about designing the extensions it
depends on your needs if anyone is able to support them.
If you don't need MapiIds [1] you're pretty much on the
safe side if you use a registered OID, prefix, registered Linked Attributes (did
I forget something?) and put those in your own class or auxclass if you want to
extend existing classes. OIDs you'll get from a registration service (like IANA)
or Microsoft, you are able to register a prefix with Microsoft, and you are also
able to get LinkIDs for the Linked Attributes from MS.
If you need MapiIds you might have to support yourself.
I've never found any way to register yourself for a certain range of MapiIds,
and they need to be unique. So no matter what you choose you never have the
assurance that never ever a vendor will use it. Did I mention that there's no
supported way of exchanging system protected attributes like MapiIDs or LinkIDs?
You are able to change them, but not supported. However PSS will tell you how to
do it if you need it.
[1]
want to see your custom attributes in the GAL? Welcome to the world of MapiIds
;-)
