I want to be able to see the requests that are sent to slapd. The problem is, no matter what debug level I set slapd to (with -d nnn), no connection info is printed.
$ /usr/sbin/slapd -u ldap -h 'ldap:/// ldaps:///' -d 16
and from a client
$ ldapsearch -x 'uid=user'
while -d 16 should print all packets sent and received... (according to slapd.conf (5) )
