FYI, before having RTFM, I thought that the only possible "include" I
can use was for schema file. It made sense to me then that OpenLDAP was
using a specific parser for schema, but I was wrong.
It seems that I have missed the part of the doc where this 'first space
requirement' is mentionned... We were lucky enough in ADS to be able to
use a contextfull parser for those schema file (we support the same
format), so we were able to relax this constraint. Supposing that ADS
behavior is to be expected by OpenLDAP is obviously a mistake ...
I wish I have some time to provide some patch for OpenLDAP to relax such
a constraint, but, eh, if I say so, that would be a damn lie !

Yeah, the problem will remain, but at least, there is a RFC for idiot
like me who don't do their homeworks... The *big* advantage to have LDIF
formatted schemas is that you won't have anymore to care about ordering
the elements inside attributeTypes and objectClasses...
Btw, we do have some LDIF format for Shcema, and I was wondering if it
won't be a good idea to try to define a common format ? I would really
appreciate if a LDIF schema file could be directly injected in both ADS
and OpenLDAP !
