AuthConfig class implements system-independent interface to configure
system authentication resources. In Red Hat systems this is done with
authconfig(8) utility.
AuthConfig class is nothing more than a tool to gather configuration
options and execute their processing. These options then converted by
an actual implementation to series of a system calls to appropriate
utilities performing real configuration.
If you need to re-use existing AuthConfig instance for multiple runs,
make sure to call 'AuthConfig.reset()' between the runs.
