  IAS doesn't implement Digest authentication.

  Use a real RADIUS server that supports something more than PEAP.

  No, they don't.  RADIUS carries additional authentication protocols.
FreeRADIUs understands all common authentication protocols.  IAS
understands the one or two that Microsoft has implemented.

  Again, don't use IAS.  It's useless.

  And you can't do Digest authentication against AD.  It's impossible.
I've just updated the compatibility matrix with Digest authentication:
