I am running OpenLdap server 2.4.59 on Red Hat Enterprise Linux release 8.8 (Ootpa) OS in standalone mode without any replication. 

# rpm -qa | grep openldap
symas-openldap-servers-2.4.59-1.el8.x86_64
openldap-2.4.46-18.el8.x86_64
symas-openldap-2.4.59-1.el8.x86_64
symas-openldap-clients-2.4.59-1.el8.x86_64
# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.8 (Ootpa)
#

Is there a way to enable multi master replication for OpenLDAP server, which is currently servicing clients in Production environment? 

Please guide me. Thanks in advance.

Best Regards,

Kaushal
