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

symas-openldap-clients-2.4.59-1.el8.x86_64
# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.8 (Ootpa)
#

# cat modify.ldif
dn: olcDatabase={2}mdb,cn=config
changetype: modify
replace: olcDbURI
olcDbURI: ldap://127.0.0.1:11389/

# ldapmodify -x -D "cn=admin,dc=corporate,dc=example,dc=in" -W -f modify.ldif
Enter LDAP Password:
modifying entry "olcDatabase={2}mdb,cn=config"
