We are running ZCS 6.0.5 OSS on Ubuntu 8.04LTS.
In trying to have more detailed LDAP logging for debugging purposes we set ldap_common_loglevel to 256 via:
zmlocalconfig -e ldap_common_loglevel=256
We also set ldap_log_level to 256 even though this setting seems to be for ZCS 5.
Just to make sure the setting is read we restarted Zimbra.
Still, nothing in the logs.
