ASN Encording of KRB-AS-REQ and REP

Hi All,
Quick question concerning the message types:
It is clear in section 8.3 of RFC1510 that the message types for KRB-AS-REQ
and REP are 10 and 11 respectively. My question is what is the ID field at
the beginning of the ASN encoded data? When I sniff the transaction between
kadmin and KerbNet I see two frames, presumably the AS-REQ and REP. The
first octet is 6A and 6B. These constants don't seem to be defined in the
RFC, can anyone tell me what these identifier octets are?

Hello people,
I'm working in authenticating Red Hat Linux users to a Windows 2000 KDC ...
What I want is to let log on Windows 2000 Active Directory users on a
machine running Red Hat 8.0.
I will appreciate if someone help me in the steps I have to follow and some
advices of more experienced people.
