I am trying to keep this conversation alive.  Kerberos V5 have S4U2Self and S4U2Proxy. 

Is there any command I can use for trying out this two protocols?

I guess I did not ask the right question. What I really want to know is how to have a service to impersonate other user via constraint delegation.
I would like to know if there is any command that I can use.
