CA-1276: Portal cannot access EDRN LDAP.

During deployment, we prompt for (or are given on the command-line) the
password for EDRN's LDAP server and set that up in the Zope database.
CA-1277: EDRN Varnish configuration requires root.

We set the "name" attribute (what an odd name) to the full path of the
Varnish spool dir to use; this avoids the default setting of
/var/varnish/"name".
