Zimbra platform leverages powerful OpenLDAP Directory Service as identity basis for Zimbra services.

Two common things that you may want to change from default OpenLDAP slapd configuration:

  1. change logging location (Zimbra default: /var/log/zimbra.log).
  2. change slapd log level.

Changing slapd logging location

Requires two changes to (a) way zimbra starts slapd, and (b) syslog config.

1. Edit file: /opt/zimbra/bin/ldap

2. Find following line:

"sudo /opt/zimbra/openldap-2.3.21/libexec/slapd -l LOCAL0 ..." 

3. Duplicate the line and comment one line (ie. add "#" to beginning -- to save original version).

4. Modify the non-commented line and remove the "-l LOCAL0" portion.

The default OpenLDAP slapd logging is to syslog facility Local4

5. Now update /etc/syslogd.conf and add following line at bottom:

local4.*     /var/log/ldap

6. Restart syslogd and zimbra (zmcontrol stop/start) for your changes to take affect.

Changing slapd log level

zmlocalconfig -e ldap_log_level=<number>

Typical example:

zmlocalconfig -e ldap_log_level=256

Note: '256' will provide insight into connections, operations, and search filters.
