Cracking a CHAP from Freeradius

[honeyfairy]

If I understand correctly, the password hash cannot be cracked without the correct Challenge [salt]  - Am I correct?

For example, if the RADIUS database has a user stored as follows:

Username: alishiazav
Password: honeyfairy

And If a user logs in with the following:

Username: alishiazav
Password: zavreski

Then, could the hash still be cracked using the method that we used, or not [due to the salt being incorrect]

Lastly, what is the ID at the end?
