This memo proposes protocol extensions to the Kerberos protocol
specification. The extension (hereafter called XKDCP) offers a new
cross-realm protocol for Kerberos. The XKDCP extension defines a
protocol between Kerberos Key Distribution Centers (KDCs) that allows
a KDC to build credentials even when the client or the requested
service is not registered in the KDC's database (but registered in
another KDC's database). The XKDCP extension defines two protocols:
XTGSP (Inter Ticket Granting Service Protocol) and XASP (Inter
Authentication Service Protocol). The XTGSP protocol can be used in
remote access scenarios to allow the local KDC to deliver credentials
for services located in remote realms. On the other hand, the XASP
protocol can be used in case of cross-realm roaming scenarios to
allow the visited KDC to deliver credentials for roaming users.

In the body type:
"FILE /internet-drafts/draft-zrelli-krb-xkdcp-00.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
