It supports various backing RDBMSes (like PostgreSQL, MariaDB/MySQL and others), allows both users that you persist in your own DB, as well as various external sources, like social login across various platforms, is an absolute pain to configure and sometimes acts in stupid ways behind a reverse proxy, but has most of the features that you might ever want, which sadly comes coupled with some complexity and an enterprise feeling.
I quite like that it offers the login/registration views that you need with redirects, as well as user management, storing roles/permissions and other custom attributes. It's on par with what you'd expect and should serve you nicely.
This one's a certified OpenID Connect Relying Party implementation for... Apache2/httpd.
Some might worry about the performance and there are other options out there (like a module for OpenResty, which is built on top of Nginx), but when coupled with mod_md Apache makes for a great reverse proxy/ingress for my needs.
The benefit here is that I don't need 10 different implementations for each service/back end language that's used, I can outsource the heavy lifting to mod_auth_openidc (protected paths, needed roles/permissions, redirect URLs, token renewal and other things) and just read a few trusted headers behind the reverse proxy if further checks are needed, which is easy in all technologies.
That said, the configuration there is also hard and annoying to do, as is working with OpenID Connect in general, even though you can kind of understand why that complexity is inherent. Here's a link with some certified implementations, by the way: https://openid.net/developers/certified-openid-connect-imple...
Please don't write your security code from scratch and lean in the direction of just gluing various tested options together.
Heya, you might want to check out FusionAuth community edition (my employer). It's very comparable to Keycloak and definitely simpler to set up and run. It's free for unlimited users.
This is hard to do, though. I hope people here will drop a lot of self-hostable combinations that work for them!
Personally, for a small/medium scale project, I went with:
