Re: iSCSI: CHAP sequence

[Steve Senum <ssenum@cisco.com>]

Hi Ambrish,

The CHAP sequence in the iSCSI draft is correct.
In RFC 1994, the CHAP_I and CHAP_C are seperate
fields sent in the same PPP PDU, but they are
still seperate fields, so in iSCSI Ofer and I
decided to send them as seperate iSCSI keys.

I have a doubt about CHAP sequence explained in draft. Under section 10.5 there
is a description like :

“

   The target MUST answer with a Login reject with the "Authentication 

   Failure" status or reply with:

 

      CHAP_A=<A> CHAP_I=<I> CHAP_C=<C>

 

   Where A is one of A1,A2... that were proposed by the initiator.

 

   The initiator MUST continue with:

 

      CHAP_N=<N> CHAP_R=<R>

 “

 

 

shouldn’t it be like:

 

“

   The target MUST answer with a Login reject with the "Authentication 

   Failure" status or reply with:

 

      CHAP_A=<A> CHAP_C=<C>

 

   Where A is one of A1,A2... that were proposed by the initiator.

 

   The initiator MUST continue with:

 

      CHAP_R=<R>

“

 

because I think the identifier (CHAP_I) and name CHAP_N) are already an
integrated part of CHAP_C and CHAP_R (the way it is
explained in RFC1994).
