This is not documented, neither in manpage nor admin guide.

Also slapd should preferably catch attempts to set them wrong, and
either adjust them or fail the change.  That's so for many config
options, but more important for interactions between options.

If that's fixed by adjusting the input values, then cachesize
configuration can be simplified for users: Given cachesize,
calculate the recommended defaults for the other cache size
variables (idlcachesize, dncachesize, cachefree).  Keep the
real variables used by the backend separate, copied/defaulted
from input variables that are set by cn=config and not defaulted.
