[Kerberos] Ticket structure

[Emmanuel Lecharny]

Hi,

I'm currently reviewing the Ticket structure, and I'm wondering why we 
do store the  encrypted data _and_ the encrypted ticket part, 
considering that the first structure is a sealed version of the second 
one ? I understand that it is an optimization as we will manipulate a 
lot the data from the second structure, but why can't we simply extend 
the Ticket class to add a new field (this encTicketpart) in the 
inherited part?

Something like :

Ticket
{
   int versionNumber;
   KerberosPrincipal serverPrincipal;
   EncryptedData encPart;
}

and

TicketWithTicketPart extends Ticket
{
   EncTicketpart encTicketPart;
}

I don't know... wdyt ?
