Thanks a lot.

With no negative impact on performance for a loaded production server?
My /var/log/debug.log was already rotating every hour and the machine
is only in a testing phase.

Actually I did
*.=debug;local4.none                            /var/log/debug.log
local4.debug                                     /var/log/slapd.log

But clearly /var/log/slapd.log is now rotating fast.
I'm using nss_ldap and a simple "id lacoste" generates more than 2 KB of logs.

I was considering keeping that setting for testing purposes and
either turn to local4.info in syslog.conf or set "loglevel=0" in slapd.conf
when in production. Is this a bad idea?

Thierry.
