To be fair, you can also have this with Kerberos 5 -- acquire a TGT
with forwardable credentials, and then tell whatever you're using to
forward them:

dr-evil:thorpej 22$ kinit -f
thorpej@SHAGADELIC.ORG's Password: 
dr-evil:thorpej 23$ telnet -axf yeah-baby
Trying 3ffe:507:183::1...
Connected to yeah-baby.shagadelic.org.
Escape character is '^]'.
[ Trying KERBEROS5 ... ]
[ Kerberos V5 accepts you as ``thorpej@SHAGADELIC.ORG'' ]
[ Kerberos V5 accepted forwarded credentials ]

yeah-baby:thorpej 1$ telnet -ax frau-farbissina
