I have the below settings as per https://www.openldap.org/doc/admin25/slapdconfig.html. I did check both /var/log and /etc/default/ on RHEL 8.7 but was unable to locate the log files. 

# grep olcLogLevel /etc/openldap/slapd.d/cn=config.ldif

olcLogLevel: 256

Is there a way to enable debug logging on openldap server and openldap client on "Red Hat Enterprise Linux 8.7 (Ootpa)" for debugging the ldap user logging issue?
