Class mit.login.KVerify 

java.lang.Object
   |
   +----mit.login.KVerify
public class KVerify
extends Object
Simple Class with two static methods. Used to Verify if a given Kerberos Username and password are correct. Note: This class is hardwired for MIT Other sites will need to change appropriate constants.

Also Note: An encryption key is included in this class, so it's source and class file must be kept confidential. Code Obsfucators may help but are not a substitute for protecting this implementation. Future versions may store the encryption key in a file which can be separately protected (which is how it should be done!)
