Last change on this file since 17387 was 14670, checked in by uli, 8 years ago

Add IKofaPluggable to update local PAU.

The new plugin enables updating of sites that have
yet no XMLRPC authentication enabled.

The plugin can be removed after updating all sites.

New sites (university-instances) do not need this
plugin at all.
