For the majority of the infrastructure i self host, we have a Samba4 server providing user services. Unless something goes seriously wrong, nobody should notice that this system is even in use, beyond needing to change ones password on a single page.
You can change your password here. If you have forgotten your password, contact me directly.
i self host a number of services, most of which can be access from either sidebar depending on whether it's personal or semi-professionally related. Most require credentials to access.
