Overview

The built-in auth (lazysite-auth.pl) and external auth proxies use the same mechanism: HTTP headers. The processor reads X-Remote-User and X-Remote-Groups regardless of what sets them. Upgrading from built-in to external requires no changes to pages or the processor.

Steps

1. Set up your auth proxy (Authentik, Authelia, etc.) with your domain
2. Configure the proxy to forward X-Remote-User and X-Remote-Groups headers to the backend
3. If your proxy uses different header names, update lazysite.conf:

auth_header_user: Remote-User
auth_header_groups: Remote-Groups

1. Change the Apache FallbackResource from lazysite-auth.pl back to lazysite-processor.pl:

FallbackResource /cgi-bin/lazysite-processor.pl

1. Replace login.md with a redirect to your proxy's login page
2. Test:

curl -H "X-Remote-User: alice" -H "X-Remote-Groups: admins" \
  https://example.com/protected-page

What stays the same

After upgrading, these all work identically:

• auth: required and auth: optional in front matter
• auth_groups: access restrictions
• [% authenticated %], [% auth_user %] and other TT variables
• Custom 403.md with context variables
• Cache behaviour (protected pages never cached)

What changes

• Login is handled by the external proxy, not login.md
• lazysite-auth.pl is no longer in the request path
• User management moves from lazysite-users.pl to the proxy's admin interface
• Cookie-based sessions are replaced by the proxy's session mechanism
• Manager access is granted by groups (the ui capability on the Groups page) and must match the group names your proxy forwards in X-Remote-Groups
