The proxy's configuration file ( authproxy.cfg ) became legendary among sysadmins—dense, powerful, and unforgiving of a misplaced bracket.

It allows you to secure older applications that only understand RADIUS/LDAP without needing to rewrite their code.

Rather than these devices communicating directly with the cloud, they talk to the Proxy. The Proxy then performs two main tasks:
