the AD LDAP interface allows you to fetch a lot of information but it
does not expose the password or password hash. It appears to be
impossible to configure AD to do so. For MSCHAP-V2 you would need either
plain text password or NTHASH of password. Since neither are available
over LDAP from AD, this is why it fails.

You would need to use AuthBy NTLM on Linux. This would provide you with
the authentication functionality. If needed, you could then use AuthBy
LDAP2 for authorization (checking group memberships etc.).
