Radius Authentication no Longer Works

I’m using NPS (i.e. microsoft radius) to authenticate Dude users which works great on 6.36.4. However, since upgrading to 6.37.5 or current, I can’t authenticate the users via NPS any more.
In version 6.36.4, the dude was using ms-chapv2 against radius but in the newer version it is trying to use md5-chap which is disabled in AD (requires reversible encryption to be enabled which is a no no).

Is it possible to change to ms-chapv2? This is a fairly important function as I have many users logging in.

This appears to be a dude issue but not a routeros issue as i’m able to authenticate to the routeros over radius with mschapv2 but not the dude with 6.37.5.

Thanks
