---------------------------------------------------------

Hi ,
As i had explained earlier ChangePasswordResult does not decode user Data properly for active
directory password change. But i found that the returned byte array represents all the policies
that are configured in the Active directory. When password changed fails it sends those values
as showing that some of them might have violated. It is like this.
this.zeroBytes = userData.getShort();
		if (this.zeroBytes != 0) {
				return;
		}
		/* Read in the rest of structure */
		int min_password_length = userData.getInt();
		int password_history = userData.getInt();
		int password_properties = userData.getInt();
		long expire = userData.getLong();
		long min_passwordage = userData.getLong() /AD_POLICY_TIME_TO_DAYS;
		if (password_properties > 0) {
			this.passwordProperties = password_properties;
		}
		if (min_password_length > 0) {
			this.minPasswordLength = min_password_length;
		}
		if (password_history > 0) {
			this.passwordHistory = password_history;
		}
		
		if (min_passwordage >= 0 ) {
			this.minPasswordAge = min_passwordage;
		}

	}

So i have fix that and now it shows correct user data. Here with i have attached the patch
for that. Ifi need to do a pull request let me know.
