Julian,
I'm not sure what you mean by this.  There is nothing I can find in the
document that states that both session types are mandatory to implement.  It
should be possible to construct "targets" that support only a discovery
session, for the purpose of "re-directs" or to construct a central "target
information server".

I would agree that "discovery" session type is mandatory to implement, but
not "normal operational session".  Furthermore, this response code should
only be returned if the initiator has requested a "normal operational
session" with a target that only supports the "discovery" session type.  It
makes no sense for a device to allow an initiator to authenticate, only to
reject a "discovery" session type.  If a target doesn't at least support a
"discovery" session type, it's not an iSCSI target...
