- Added logging for invalid username attempts to provide more detailed failure reasons.
- Removed "login attempt" log entries to reduce log volume and focus on final verification results.
- Retained logging for invalid password and successful user authorization for clarity.
- Added getRealRemoteIP function to retrieve the real client IP address when behind a reverse proxy.
- Updated authentication logging to use the extracted IP instead of r.RemoteAddr.
- Ensured compatibility for both proxy and non-proxy setups, falling back to r.RemoteAddr when X-Forwarded-For is not present.
Directory makes it more clear of what it is. In addition, this will make it easier when
allowing for multiple directories in the future, since we can just name it 'directories', which is more clear than 'scopes'.
