I use Keycloak and OpenLDAP, but if I was setting it up again I’d probably just use Authentik

Recently signed up with https://www.migadu.com, been great so far

I didn’t feel like they were too badly communicated, but maybe that’s just means my standards for corporate coms isn’t very high.

I’m currently testing https://www.migadu.com/index.html as a replacement - $19/year seems like a pretty good deal.

I’ve been with gandi.net for over a decade, have nothing but good things to say about them.
