WebWhat is Kerberos? Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology. Kerberos is available in many commercial products as well. Webcontrols the set of enctypes that a service will permit for session keys and for ticket and authenticator encryption. The KDC and other programs that access the Kerberos database will ignore keys of non-permitted enctypes. Starting in release 1.18, this setting also acts as the default for default_tkt_enctypes and default_tgs_enctypes.
