For better GDPR compliance and security I'd like to recommend using
NT-Password for authentication (sambaNTPassword in LDAP). These
passwords stored as NThashes are fully compliant with MSCHAP
authentication, but you have to store them in LDAP (or even database),
so you have to store and chage both: SHA hashed userPassword and NT
hashed sambaNTPassword for each user. The drawback is that such a
solution requires 3rd party password updating tool for LDAP.
