Good to hear it.

Time to wake up now, Ludo.  :-)

I understood from previous exchanges with Kurt that RFC2307bis couldn't 
be standardised as it stands because it attempts to redefine attributes 
or classes from RFC2307, and you're not allowed to do that.  However, if 
people are already using RFC2307bis then you'll be in a catch-22 
situation, not being able to fix those problems without breaking it for 
existing users.  Ergo, RFC2307bis is dead in my opinion and will never 
be a standard.  So let's not cry over spilt milk, let's move on and 
embrace DBIS!! (Ok I'm stirring trouble here, and I'm biased, but I have 
a valid point).

Thanks Michael, I'm aware of all of the various tracks, but wouldn't 
want DBIS to fall into the same trap as RFC2307 did, being released as 
"experimental" but then being adopted everywhere, then being a real pain 
to fix up later.  I do want DBIS to become a proper ratified standard, 
and for that to happen, as Kurt said in his posting in December last 
year, I need the advice of an area director.  I approached Barry Leiba 
on this very subject in August, and it is partly because I approached 
him that the LDAP working group is being kick-started again.  But with 
DBIS off the agenda!

Indeed, and I followed Kurt's advice as given in msg02081 above, hence 
Barry's intervention.

Accepted, design by committee doesn't work.  But IETF working groups are 
not supposed to be designs by committee.  You speak of complex 
documents, but I don't see that the DBIS documents as complex, I think 
that is a rather subjective label.  Define complex?  I would be happy to 
make it less complex if people could suggest what they think is 
currently complicated about it.  If the IETF is unable to work with 
documents of the size of DBIS, then something is broken in the process I 
think, because each individual DBIS document is a lot smaller than 
RFC2307 (which I broke up to make it more manageable!).

1. Is not hard to do, I think I could find people.
2. Is the bit I still don't understand.  Where is this rule written 
down?  I'm all for due process, and I can work with due process, esp. if 
it is well documented, but at the moment I feel that people are just 
shifting goal-posts to keep DBIS out.
