+It supports ticket refreshing by screen savers, configurable
+authorization handling, authentication of non-local accounts for network
+services, password changing, and password expiration, as well as all the
+standard expected PAM features.  It works correctly with OpenSSH, even
+with ChallengeResponseAuthentication and PrivilegeSeparation enabled,
+and supports extensive configuration either by PAM options or in
+krb5.conf or both.  PKINIT is supported with recent versions of both MIT
+Kerberos and Heimdal and FAST is supported with recent MIT Kerberos.")
