Hello Brian!

AFAIK, it will work. Your RADIUS server will retrieve the hash from LDAP 
and do the validation locally. So FreeIPA has no way to say the password 
is expired.
When the user tries to obtain Kerberos ticket he will be forced to 
change the password and NTLM hash will be also regenerated.
