Questions on kerberos (principal, service, renew command)

Hi all,

  I have the following questions by looking at the kerberos packets
(Windows login) through ethereal:

  1. There are several service names, such as host, ldap, LDAP, cifs,
etc
      What is the difference between ldap and LDAP?
      What does service, host, do?

  2. There are some TGS-REP with principal name, hostname$. What does
this mean?

  3. After a TGS-REQ renew request (KDCOption == 0x02), then a TGS-REP
with kbrtgt. Then there is always another TGS-REQ and TGS-REP for
kbrtgt service. Why is that?

Many thanks
Joe
