query on MS-CHAPV2

Hi, I am using Freeradius 1.1.4 for testing my client for MS-CHAPV2. I am not clear with the final step of the MS-CHAPV2 authentication i.e. After receving MS-CHAP2-Success from radius server, which contains 42 byte of string, what client should do? From the draft, it looks client should use these string to authenticate server. But it it not clear from draft, how is generated by the server. Similary, how client should generate the same and authenticate the server ? Thanks in advance. --------------------------------- Sucker-punch spam with award-winning protection. Try the free Yahoo!
