Maintenance mode

I just stumbled over my old article on locking out users and felt, that it is a bit outdated. The mechanism described there is only suitable for CQ3 and CQ4, but is not applicable for CQ5, because there is no “post” user, and the complete access control mechanism has changed.

In CQ5 it is incredibly easy to install ServletFilters (thanks OSGI and Declarative Services); so I wrote a small servlet filter, which blocks requests originating from users, which are not whitelisted. That’s a nice solution, which does not require any intrusive operation such as changing ACLs or such. You just need to deploy a tiny little bundle, put “admin” on the whitelist and enable the maintenance in the Felix webconsole. That’s it.

I will submit this package (source code plus compiled bundle) to the Day package share, licensed under Apache 2.0 License. It may take a bit, but I will place it to the public area, so you can grab it and study the source (it’s essentially only the servlet class).
