I used "radiusd -Xx" to display the datetime and figure out what the first and what the second login.
I posted the full debug because Phil asks me. 
The problem I am having is probably related to the mschap module.

"You keep posting useless debug output, or tiny pieces of the debug
output"... this is your opinion, with the ldap module my debug output has been useful for you !!

As regards the current problem, I'll manage to find a solution.
Thanks for the help

  Please use a txt file next time.  The output is text.  Also, use
"radiusd -X", not "radiusd -Xx".  It simplifies the output.

  What I see is ntlm_auth returning login failure.  Then, the server
sends a challenge, and nothing else happens.

  There's no Microsoft change password attribute in the debug output,
either.

  So... it's impossible to help you.  In order to debug password change
issues, we need to see debug output with password changes in them.

  I would suggest that *you* read the debug output, too.  Look for
password change requests.  It isn't hard.  Then, post those.

  You keep posting useless debug output, or tiny pieces of the debug
output.  This tells us that you're not interested in doing work yourself
to solve the problem.  If that's true, then we're not interested in
working on it, either.
