This is a quick attempt at a SIA module for Kerberos. To install this
you will have to do the following:
* Make sure libsia_krb4.so is available in /usr/athena/lib
* Copy krb4_matrix.conf to /etc/sia
* Apply security.patch to /sbin/init.d/security
* Turn on krb4 security by issuing `rcmgr set SECURITY KRB4' and
`rcmgr set KRB4_MATRIX_CONF krb4_matrix.conf'
* Digital thinks you should reboot your machine, but that really
shouldn't be necessary. It's usually sufficient just to run
/sbin/init.d/security
Users with local passwords (like root) should be able to login safely.
