Parses a KRB_AP_REQ message, returning its contents.
server specifies the expected server's name for the ticket.
sender_addr specifies the address(es) expected to be present in the

A replay cache name derived from the first component of the service name
is used.
The default key store is consulted to find the service key.
authdat->ticket and authdat->authenticator are set to allocated storage
structures; the caller should free them when finished.
