- Added system `radius` group - Added `mandatory` and `optional` modes for RADIUS - Improved PAM config for RADIUS New modes: - `mandatory` - if RADIUS answered with `Access-Reject`, authentication must be stopped and access denied immediately. - `optional` (default) - if RADIUS answers with `Access-Reject`, authentication continues using the next module. In `mandatory` mode authentication will be stopped only if RADIUS clearly answered that access should be denied (no user in RADIUS database, wrong password, etc.). If RADIUS is not available or other errors happen, it will be skipped and authentication will continue with the next module, like in `optional` mode.
