ERROR: Shared Secret is incorrect

[Network RADIUS]

** What does a "Shared secret is incorrect" error mean? 
** (And its close cousin: "WARNING: unprintable characters in password”)
--------------------------------------------

The root cause for both messages is the same, and is unambiguous: The shared secret on the RADIUS server and the NAS are not the same.

However, there can be some confusion because, depending on what information RADIUS receives in the packet header, you will see either the error message or the warning.

There are also several scenarios where system administrators might think that the shared secret is the same on the RADIUS server and the NAS, when in fact, they are not.

This article will explain why those messages turn up in slightly different contexts, and how you can fix the problem.
