Several comments from various PacketCable team members: "Kerberos-5 protocol (RFC-1510) does not define any specific backoff and retry algorithm. Consequently, all specifics of the backoff and retry mechanism for AS- and AP-exchange are defined by the PacketCable security spec, and involves the parameters supplied by the DHCP Server to parameterize the Kerberos Authentication for Provisioning Service." Further... "None of the subsequent IETF drafts such as Kerberos clarifications define it either - I don't think that a specific retry mechanism was ever considered to be in scope of the Kerberos IETF working group." Thus the need for the sub-options. >In terms of how to proceed, you might consider posting proposed text >for each of the items prior to reissuing the draft.
