    abstract =  {This document specifies a protocol for obtaining cross-realm Kerberos tickets using existing, related protocols: kerberized certification authorities (kx509) and public key cryptography initial authentication in Kerberos (PKINIT). The resulting protocol has a number of desirable properties, primarily that it allows Kerberos to scale to large numbers of realms.},
