Dear freeradius users,

I have the following error for one authorisation:
"chap: ERROR: &control:Cleartext-Password is required for authentication" as you can also see in the debug text.

Usually this error is related to a missing password or a wrong password.
However I am using almost the same authorisation procedure on another freeradius platform
And on the other platform the authorisation worked well without problems.
So my question is
Are there other known grounds to have the above error ?

mit freundlichen Grüssen  /  Best Regards
