Example—Setting Up Parallel Propagation

Using the example in Figure 8–2, the master KDC's kprop_script entry would look similar to the following:

0 3 * * * /usr/lib/krb5/kprop_script slave-1.example.com slave-4.example.com

The slave-1's kprop_script entry would look similar to the following:

0 4 * * * /usr/lib/krb5/kprop_script slave-2.example.com slave-3.example.com

Note that the propagation on the slave starts an hour after it is propagated by the master.

The kpropd.acl file on the propagation slaves would contain the following entry:

host/master.example.com@EXAMPLE.COM

The kpropd.acl file on the KDC slaves being propagated by slave-1 would contain the following entry:

host/slave-1.example.com@EXAMPLE.COM
