This is now fixed in HEAD overlays/pcache.c. The bug occurred because the 
cache was seeing a child entry first, and so the dc=justillusion.net object 
got created as a glue entry. Later when the actual dc=justillusion.net entry 
was received, the modify to store its true values in the cache DB failed 
because it needed the manageDSAit control.
