Issue:

If you have authentication issue with AD after enabled MSChapv2.

Checking:

1)Please capture packets when client tried to authenticate. You will find AD reject Samba request.

Root cause:

1)Due to Legacy USG only supporting SMBV1, if your AD server has disabled SMBv1 for security concern, it will result in a failure.
