[FEAT] Add Tailscale NGINX Auth (Optional: Fallback to ldap auth, Authelia, Authentik

[bakerboy448]

Is this a new feature request?

• I have searched the existing issues

Wanted change

incorporate https://tailscale.com/blog/tailscale-auth-nginx/ thus allowing SSO via tailscale with fallback with fallback to existing auth methods

Perhaps incorporated via a docker mod?

Reason for change

Simplified login and another auth method

Proposed code change

server additions

    # enable for Tailscale (requires tailscale-location.conf in the location block)
    #include /config/nginx/tailscale-server.conf;

location addions

        # enable for Tailscale (requires tailscale-server.conf in the server block)
        #include /config/nginx/tailscale-location.conf;

tailscale-server.conf

location /auth {
  internal;

  proxy_pass http://unix:/run/tailscale.nginx-auth.sock;
  proxy_pass_request_body off;

  proxy_set_header Host $http_host;
  proxy_set_header Remote-Addr $remote_addr;
  proxy_set_header Remote-Port $remote_port;
  proxy_set_header Original-URI $request_uri;
}

# enable for ldap auth fallback auth
#location @fallback_to_ldap {
#    include /config/nginx/ldap-location.conf;
#}

# enable for Authelia fallback auth
location @fallback_to_authelia {
    include /config/nginx/authelia-location.conf;
}

# enable for Authentik fallback auth
#location @fallback_to_authentik {
#    include /config/nginx/authentik-location.conf;
#}

tailscale-location.conf

        # Tailscale authentication
        auth_request /auth;
        auth_request_set $auth_user $upstream_http_tailscale_user;
        auth_request_set $auth_name $upstream_http_tailscale_name;
        auth_request_set $auth_login $upstream_http_tailscale_login;
        auth_request_set $auth_tailnet $upstream_http_tailscale_tailnet;
        auth_request_set $auth_profile_picture $upstream_http_tailscale_profile_picture;

        proxy_set_header X-Webauth-User "$auth_user";
        proxy_set_header X-Webauth-Name "$auth_name";
        proxy_set_header X-Webauth-Login "$auth_login";
        proxy_set_header X-Webauth-Tailnet "$auth_tailnet";
        proxy_set_header X-Webauth-Profile-Picture "$auth_profile_picture";

        # enable for ldap auth fallback auth 
        # error_page 401 = @fallback_to_ldap;

        # enable for Authelia fallback auth 
        error_page 401 = @fallback_to_authelia;

        # enable for Authentik fallback auth 
        #error_page 401 = @fallback_to_authentik;

swag volumes assuming tailscale nginx auth and tailscale on host

      - /var/run/tailscale.nginx-auth.sock:/var/run/tailscale.nginx-auth.sock
      - /run/tailscale.nginx-auth.sock:/run/tailscale.nginx-auth.sock

Looks like it's a go binary, good news for alpine. I like the concept. I agree a mod would be a good idea.
