ReadyAPI On Prem license server - LDAP settings

We are setting up the On Prem license server for ReadyAPI, following the instructions given at https://support.smartbear.com/licensing/docs/activate-and-use/private-networks/onprem-license-server/settings.html.

The instructions do not have any example of the required LDAP entries. After several experiments we managed to get the On Prem server to accept our Base, User Group DN and Admin Group DN settings without reporting an error.

However, the license manager still will not allow us to assign licenses to users as instructed in https://support.smartbear.com/licensing/docs/activate-and-use/private-networks/onprem-license-server/assign-to-users.html .  The user name will not populate from our Active Directory list, so the "Assign" button is never enabled.

Can somebody please provide an example working entries for the LDAP settings and any other tips for getting this On Prem license server to work?
