I just upgraded my 2.4 CVS from earlier this year to 2.4.13, but can't get the accesslog overlay to log _both_ reads and writes at the same time!
Either one by itself works fine, but not combined. If I specify 'reads writes', all I get is reads. Same if I specify all the operation types ('add delete modify modrdn compare search abandon bind unbind').
Actually, not 100% true - I get the deletes, but nothing else (other than the read types).
