Issue an Access Challenge to retry password

[Stefan A.]

Gurus,

I want to give the user a second chance to type his password correctly by
using a radius challenge.
I'm not sure how to do this and did not find anything about this in the
documentation nor in my stored email of this list.

What should happen:

The user tries to authenticate using his User-Name and Password.
The user makes a typo in the password.
The RADIUS Server will send an RADIUS Challenge, having a Reply-Message
'Good Morning. Please retry your Password!'
The user retries... This time using the right password
The User will be granted access.

How would I configure this in the user file?

Any help or advice to a related part of the documentation will be
appreciated.

Thank you.
Stefan
