slapcat, PROXIED attributeDescription inserted, and cron jobs

["btb@bitrate.net" <btb@bitrate.net>]

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

>slapcat -b 'cn=config' -l 'config.ldif' > /dev/null
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
