slapcat, PROXIED attributeDescription inserted, and cron jobs

hi- i'm running slapcat from a daily cron job to back up cn=config and other databases. i've recently updated from 2.4.21 to 2.4.23, and notice now in the output of slapcat, messages such as PROXIED attributeDescription "OU" inserted. PROXIED attributeDescription "DC" inserted. a bit of searching seems to indicate that these shouldn't be cause for concern, and are just informative messages. since these messages are written to stderr, cron sends email every time it runs slapcat. if they're not errors, do they maybe belong in stdout rather than stderr? alternatively, can these messages be suppressed? according to the man page, there doesn't appear a way to do so. thanks -ben
