Ok, I found this - https://www.linuxserver.io/blog/2020-08-26-setting-up-authelia.
Which, if I’m reading it correctly tells me that SWAG (Secure Web Application Gateway) is essentially a web server, reverse proxy with lets encrypt support. It doesn’t seem to do any authentication.
Authelia is a component of an identity and authentication solution that provides single sign on and 2FA but, crucially, does not include a user directory, by default it uses a YAML file but can be connected to an LDAP server - https://www.authelia.com/overview/authentication/first-factor/
Which I think goes towards the point in my original post - none of this is simple so I’d like a nice explanation that helps me understand what I need running, how they work together and what settings to use.
Thanks. I have all of that. I’ve been at this for a while and am now looking to move to centralised authentication and access management because I’ve got everything else working as I want it. It’s just not ideal to have to maintain seperate logins across each of the services that I’m running. Hence starting to look at authentication. I know it’s complex and the original post was wondering if there is a nice simple introduction to the subject matter.
