AFS uses Kerberos to do complex mutual authentication which means that both the service requester and the service provider have to prove their identities before a service is granted.
-Originally AFS shipped with it's own version of a Kerberos, called "KAS." KAS still ships at this time (1.4.2 release) but is depricated in favor of using a true Kerberos 5 implimentation. [[OpenAFS]] does not currently ship with a K5 install; it is up to the administrator(s) to choose a version (either MIT's or KTH's "Heimdal") and install it. [[OpenAFS]] will happily work with either.

[[OpenAFS]] does not currently ship with a krb5 install; it is up to the administrator(s) to choose a version (MIT krb5, Heimdal, Active Directory, etc) and install it.

-No. AFS was designed to work over TCP/IP.
+No. AFS was designed to work over UDP/IP, and does not use TCP/IP.

+There is some work being done (see
