Chapter 13. Troubleshooting
An efficient ICT Services department is almost invisible. Infrastructure just works as expected and users are blissfully unaware of the system layers that shield them from the underlying hardware. Even a little upheaval in the usually frictionless connectivity can seriously disrupt business operations and jeopardise business continuity.

- Why FreeRADIUS may be slow
- Why FreeRADIUS would stop working
- Why FreeRADIUS would fail on a RADIUS client's requests
- Why a user would not authenticate
