When switching to ksmbd from Samba, the wsdd2 daemon will refuse to start. This is due to the service file is written to bind to the smbd service that is not installed anymore after removing Samba.
To fix the issue simply copy the file from /usr/lib/systemd/system/wsdd2.service to /etc/systemd/system/wsdd2.service and remove the line from the file that reads BindsTo=smbd.service.
