  The server does that automatically.  The Cleartext-Password is the users *correct* password.

  User-Password is what the person entered in order to get online.  It might be the same (if it's correct), or it might be different (if it's wrong)

  CHAP-Password is a CHAP calculation of what the person entered in order to get online.  

  MS-CHAP is an MS-CHAP calculation of what the person entered in order to get online. 

  For CHAP and MS-CHAP, the server takes Cleartext-Password, and calculates the CHAP or MS-CHAP information.  If it the two things match, the user must have entered the right password.
