Hello, i´m here again.

> It looks better, but don´t work. Now, the challenge pass-through to the MSCHAP-V2 Handler, but it shows the same error message:

>Christian already took care of most issues, I'll try to continue.

>You are currently using RewriteUsername. That may cause problems if
>Radiator and the client calculate MSCHAPv2 challenges and responses

>However, it looks like you are using mikem as the username and it does

I have tried it. Using rewrite username with $1 (mikem), $2 (anonymous) and without "rewriteusername". And the result was the same.

>About your clients file. If you really had this:
>mikem user-password = xxxxx
>you would get an error since user-name is not written as User-Password.
>The error would be something like this: "Check item user-password
>expression 'password' does not match '' in request" for a line like this
>in the users file:
>mikem user-password = "password"

Sorry, it was a writing-mistake. My user file is correct and works with AAA.

Any troubleshooting idea?

 Regards and thanks in advance,
