+# Configuring Kerberos
+
+Configure Kerberos, you ask? But I'm not using Kerberos!
+True, but the Kerberos library is kind of self-centered at the moment and doesn't believe anyone would ever want to not use Kerberos.
+So, it requires that servers be able to set up Kerberos even if they never use it.
+Please see also a bug.
+So you want something like
+
+Contents of /etc/krb5.conf:
+
+    [libdefaults]
+        default_realm = YOUR_DOMAIN_ALL_CAPS
+
+Then run ktutil
+
+    addprinc --password -p host/hostname.your_domain@YOUR_DOMAIN_ALL_CAPS -k 1 -e aes256-cts
+
+Enter a password of your choice
+
+   wkt /etc/krb5.keytab
+    quit
+
+Then <code>chmod a+r /etc/krb5.keytab</code>. Note that would be a very bad thing to do if you actually were using Kerberos. It may still be a bad thing to do if you have services enabled that can potentially use Kerberos.

+            }

+        EOF
+
+$secret is the secret you share with the radius server, i.e. the "secret" entry in FreeRADIUS configuration "client" clause.

 Todo:
-* configure libradsec
 * Set up RADIUS
