October Review: TOTP in Horde

I have been working on multiple things recently.

Kronolith Web UI: Appointment Cancellation Bug

Fix an annoying bug where internal user attendees get cancellation mails when an appointment is updated by the owner. This only seems to happen from the Web UI, not from CalDAV. I already analysed how this is happening. The fix is going to be a little bigger as I do not want to invest in the legacy infrastructure (socalled “Imples”) and use the opportunity to use a more modern approach. Work is in progress.

New Material UI based frontend for passwd.

I have worked with the team on a Material Design based UI. It uses ReactJs and Typescript and the new horde/http_server library and it is very different from existing Horde UIs. Do not expect it to blend well with the existing horde look&feel. The whole thing is a proof of concept and is an alien as the DIMP UI was back in Horde 3. This proof of concept still lives in a public feature branch and if you want to try it, you need to enable a new setting in the Preferences Screen.

Two-Factor support in Horde Base and a TOTP library

More and more online services start using two-factor authentication for improved security. Along with a password, users have to enter some passcode they read from a keychain fob device or from an app on their phones (like Google Authenticator).

I have started a new library horde/otp which implements TOTP and other styles of passcodes used as a secondary authentication factor. The library needs some additional glue code in horde/core and horde/base which still has to be built. I would have liked to finish this in October but there is only so much time.

Improved horde-installer-plugin

The composer plugin for Horde has received some refactoring and enhancements. The current feature branch offers a custom command in the composer CLI . This custom command rebuilds the relevant configuration files when you move your Horde installation after running the install/update commands. There are also some minor changes to the way configurations are written. End users should not notice.

DNS library

B1 Systems have finally opensourced a DNS library for the Horde ecosystem. It has been used internally for some years. The library can serve as the DNS building block of an IPAM system, but it also has an adapter to apply changes to the Amazon Route 53 service.

PHPStan support

Beginning this month, libraries and apps will gradually introduce the static analyzer tool phpstan. The tool will run as part of the CI pipeline and detect various types of code imperfections which potentially can mean hard-to-detect bugs. The findings will be addressed as time permits.
