Because I need an OpenLDAP environment for testing purposes I wrote three Ansible-roles to create an environment with three OpenLDAP-servers, one provider and two consumers.
Everything you need are three Debian-VMs with ssh-rootlogin with password. This will  be revoked at the end of the first script, after setting up a sudo-user.
The name of the first role is setup_server, this role will do the first equal steps on all servers:

• All the needed packages will be installed
• An ansible user will be created on all servers
• The public-key from ansible-user on the control-host will be copied to all servers
• Setting up sudo with no-password for the ansible-user
• The certificate for all servers will be copied to all servers, depending on the hostname (see README.md)
• Some ACLs will be set
• Setting the loglevel 

After the first run the root-login via ssh with password is no longer possible. 

The second role setup_provider will do the following tasks:

• Loading the sycprov-modul and configure it
• Create a user for replication with read-permission to all objects and all attributes
• Create a user with write-permission to all object and all attributes this user will be used to manage the objects
   

The third role will setup the two consumers:

• Configuring the replication
