How this works: When a PHP report runs in preview mode, it reads these credentials from /etc/astguiclient.conf — the same path Vicidial uses on production servers. When the same PHP file is dropped into a real Vicidial server, it transparently uses that server's own astguiclient.conf. No code changes required.
