syslog-ngからの一部のメッセージの除外
次のLDAPログエントリなど、syslog-ngによるログからいくつかのメッセージを除外しようとしています。

これらのメッセージを除外するために使用しようとしているこのsyslog-ngフィルターがあります。
filter f_not_ldap { not match("slapd" value(PROGRAM)); };
log { source(s_udp); filter(f_not_asa); filter(f_not_dbg); filter(f_not_ldap); destination(d_messages); destination(d_logserver); };
しかし、それらのslapdエントリはまだ私のリモートログサーバーに送られます。誰かが私が間違っていることを教えてもらえますか？これらのslapdエントリを除外するために他に何をする必要がありますか？
前もって感謝します。
編集：これがsyslog-ng.conf全体です：
@version: 3.3
@include "scl.conf"
# Syslog-ng configuration file, compatible with default Debian syslogd
# installation.
# First, set some global options.
options { chain_hostnames(off); flush_lines(0); use_dns(no); use_fqdn(no);

bad_hostname("^gconfd$");

184行目でした。次のように変更しました。
log { source(s_src); destination(d_logserver); };
に
log { source(s_src); filter(f_not_ldap); destination(d_logserver); };
そして今、LDAPログは私のログサーバーに送られなくなったので、これは修正されました。
filter f_not_ldap { not match("slapd" value(PROGRAM)); };
これで、次のように置き換える必要があります。
filter f_not_ldap { not message("slapd"); };
メッセージはバージョン2.2から利用できます
