"What is the support status of the LDAP servers shipped with Red Hat Enterprise Linux?" says:
Important: Starting with Red Hat Enterprise Linux 7.4, the openldap-servers package has been deprecated and will not be included in a future major release of Red Hat Enterprise Linux. There is a variety of open source tools and solutions that provide directory services. With the raise of the adoption of the Identity Management in Red Hat Enterprise Linux (IdM) solution and decline in use of the OpenLDAP server for the enterprise use cases Red Hat made a decision to focus on the technologies that Red Hat historically had deep understanding, expertise and been investing into for more than a decade. Focusing on Red Hat Directory Server and IdM offerings would allow Red Hat to better serve the customers of those solutions and increase the value of subscription. OpenLDAP server will be supported till the end of the life of the RHEL7 release following the Red Hat Enterprise Linux Life Cycle.
Emphasis Mine
So, I cannot use OpenLDAP under Oracle Linux 8! I will have to use OID instead.
Download software from here.
Installation instructions can be found here.
The documentation is not very clear about what I have to install for OID. I will use the instructions in "Oracle Database Application Security: With Oracle Internet Directory, Oracle Access Manager, and Oracle Identity Manager" instead.
I have installed OEL 8 on a VirtualBox VM with 4 GB RAM and 50 GB hard disk. The software installed was "Server with GUI".
dnf group install -y "Server with GUI"
