- [[KerberosIV]] -- the original MIT implementation, and [[Krb4KTH]], an export version of [[KerberosIVMIT]] (aka "bones"), but with encryption support put back in by the fine folks at KTH.
- [[KerberosV]] -- version five of this protocol has numerous improvements over version four and is available from many sources: MIT, DCE, Microsoft (aka [[ActiveDirectory]]) and [[HeimdalKTH]].
-The consensus these days is to use [[KerberosV]], even though lacking native support for V5, AFS still needs various conversion and migration tools.
+The consensus these days is to use [[KerberosV]], even though lacking native support for V5, AFS still needs various conversion and migration tools. See [[KerberosAFSInstall]] for (what will be) a step-by-step procedure to install a new [[OpenAFS]] cell where authentication is handled by a [[KerberosV]] realm.
For [[KerberosV]], there are two main open-source solutions for Unix: [[KerberosVMIT]] and [[HeimdalKTH]]. A quick comparison of the two:
- How to configure various authentication servers to issue tickets (tokens) with lifetimes longer than 25 hours.
- [[IntegrationWithNIS]]. See the [[GeneralFAQ#1_05_d_Improved_security]], but basically you use NIS vis NSS for names of users and Kerberos via PAM for authentication. There is still the question of integrating group management.
- [[OtherGroupServers]] are not well integrated as far as I know. The big ones are [[ActiveDirectory]] and [[NIS]] and maybe some LDAP systems. While one could imagine wrapping a [[PtServer]] interface around such a thing, there are probably some features that would make seamless integration difficult. Has anyone seriously looked into this?
