Sorry. Looking through the code of extract_dbstats.pl which output
I cut-and-pasted, the '40960' is sum of previous values...

I've been going back and forth betwen '4' and '4096' so many times,
I've started to mix up my own code...
Sorry about this.

For all of the people out there writing their own personal pages with
tips/notes/whatever - PLEASE consider submitting them as documents for
the OpenLDAP site to publish first/instead. Then there is at least
some possibility that the content can be checked for correctness, and
also some possibility that the content will be maintained and kept up

I especially like the last part of the last sentence...
I continue to think that the OpenLDAP documentation sucks...

I'm PERFECTLY comfortable in reading technical English. I usually read
that better than my native language (not an exaggeration!).
As long as the documentation is CORRECT, I have no problem with it. You
think it's 'perfectly clear' because you know the inner workings of
the software's you're coding for.. I couldn't care less! I'm a user/admin,
I have no need/will to know how it works behind the scene with structures
back and forth, if they're int's, float's or what not.
I need a working calculation example. Using '4KB' as number and/or not
explaining (CLEARLY!) where the number come from (with command line
examples etc) will just look like magic, and will only complicate things
All mails asking the same question over and over again PROVES this! EVERYONE
seem to have problems in getting KerberosV+CyrusSASL+OpenLDAP working,
so the 'rubbish' (sorry, I think it is) that the OpenLDAP documentation
is sufficient/good/whatever don't hold truth...
NO ONE have 'complained' about _MY_ documentation/book (more
than the obvious spellingerrors etc :). It have helped EVERYONE
trying to get it working. It is written in _HUMAN_ english, not
Someone said that 'never let a technician write documentation'..
I couldn't agree more!
isn't much better. I agree with you (in the msg00129 above) that
And anyone who blindly follows such unqualified advice is an idiot.
My intention is to rectify this, but I must understand the subject
myself, before I can give ANY advice etc and I hope you can (continue)
to help out here... My fault above (kbytes versus bytes), but I
would like to defend myself (very vaguely :) that all those numbers
just made my head spin :)
