What is the curent state of LDAP?

Hello, everyone! I was wondering about the current state of using LDAP authentication. I am using Windows AD and RHEL IDM at home and would like to auto-deploy the UrBackup client, allowing users to restore their own files. In UrBackup, when navigating to the LDAP settings, there is a warning not to expect LDAP to work. Is there somewhere I can follow the progress of the LDAP implementation, or can someone guide me to more information? I haven’t found any documentation for LDAP with UrBackup either.
