!!! Overview
[{$pagename}] represents the [client] [request] within the [AS Exchange]

[{$pagename}] is the initial [authentication] [request], the [Kerberos] [client] ([kinit]) asks the [KDC] (more specifically the [Kerberos Authentication Service]) for a [Ticket Granting Ticket]. The request is completely [Plaintext] and looks like this:
\\

AS_REQ = ( [PrincipalClient|UserPrincipalName] , [PrincipalService|ServicePrincipalName] , IP_list , Lifetime )
\\

IP_list may also be [null]. In this case the corresponding ticket can be used by any machine. This resolves the problem of those [Kerberos] [clients] under [NAT], since their request would arrive at the service with a source address different from that of the requesting user, but the same as the router making the [NAT].
Instead, in the case of machines with more than one network card, IP_list should contain the [IP address]es of all the cards: in fact it would be difficult to predict beforehand with which connection the server which provides the service would be contacted.
