  Read the debug log.

(72) mschap: WARNING: No Cleartext-Password configured.  Cannot create
(72) mschap: WARNING: No Cleartext-Password configured.  Cannot create

  Why is there no password?  I have no idea.  You deleted all of the debug output from packet (72) which shows where the password came from.  Which also mans we don't know *why* the password lookup failed.

  Please follow the instructions on https://wiki.freeradius.org/list-help

  There is no need to post debug output from an authentication session which succeeds.  It doesn't help.  Post the debug output for a session which fails.  *ALL* of the debug output.

  Editing the debug output is like taking your car to a mechanic and saying "something's wrong, but I'm not going to tell you what.  You have to figure it out and fix it"
