yep, thanks Dean - quite useful, as was the whole thread. It's always interesting to see how much discussion a "simple" question can cause :-)

Brett and I just had, the result and content of which turned up some interesting (to me at least) implementation details. The short story is - * DNTs (to me) are _not_ a component of the directory - they _are_ a component of the layer that bridges the two (dblayer) - to Brett, I believe he sees them within the sum of "what is the directory" * DNTs (to both Brett and I) are not part of ESE * DNTs are limited (as Eric says) to 2^31 (~2.1 billion rows) * DNTs are not reusable I hope the summary and conversational text inline proves useful. -- Dean Wells MSEtechnology * Email: [EMAIL PROTECTED] http://msetechnology.com > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Brett Shirley > Sent: Tuesday, April 18, 2006 5:11 PM > To: [email protected] > Cc: Send - AD mailing list > Subject: RE: [ActiveDir] User Accounts > > > Dean, I didn't understand this comment ... > > But, dude, seriously, you weren't aware that AD's ESE used > a 32 bit DNT? > > Methinks perhaps you're muddling in the realms of personal > interpretation > ... though I'm quite certain you'll argue > that too ...

Not at all ... but IMO, neither does the directory ... and per our IM, the dblayer knows what they are (after all, DNT = distinguished name tag ... blatantly not an ESE term ... and dblayer = database layer ... not a directory term ... hmmm) > A DNT is an entirely AD concept, ESE has no idea what a DNT > is. Nod. > ESE also has no concept of linked-values, or the > link_table. Now this was news to me, so here's the summary: ESE has tables + columns + indices over columns. The dblayer forms the bridge between two technologies, one molding the behavior of the other (dblayer molds ESE). ESE maintains no referential integrity, the dblayer does this ... including link-pairs <-- this part was especially surprising to me. > This is the 2nd time you've confused the AD > dblayer (what maintains the AD schema on an ESE > database) and the ESE database layer. Don't know that I'd agree with that since on neither occasion was the dblayer specifically referenced .. but it's moot for the moment since I'm still mulling over whether my new-found knowledge pertaining to link-pairs influences my opinion on where DNTs lie; directory or database.
