Kolab, SSO and Second Factors

Kolab Groupware is a collaboration suite establishing the integration of various applications you know already; Most prominently, these include 389 Directory Server, Postfix, Cyrus IMAP and Roundcube. Together, these applications would comprise a simple mail system that, in terms of functionality, would fall short of “groupware” and “collaboration” functionality. Side-note: Cyrus IMAP has added CalDAV,… Continue reading Kolab, SSO and Second Factors

A Flask Mega-Tutorial: Intermezzo II

I now have a bit more information on what it is I will be achieving, and I wanted to share the roadmap and horizon of the project I’m undertaking. The software development project is called PACK — a portal or panel for administration of Kolab Groupware. For our current most important deployment, Kolab Now, this… Continue reading A Flask Mega-Tutorial: Intermezzo II

A Flask Mega-Tutorial: Part III

Welcome back to my mega-tutorial on Flask. If you’re following along with Part I and Part II, you should already have a minimal Flask application that doesn’t really do anything meaningful.

Over the course of years, I’ve met many people that use GIT too frequently to not have their setup include the convenience of a… Continue reading Use the Prompt, GIT!

Thou Shalt Not Use OAuth

TL;DR: Do not use OAuth to “Sign in with…” without a second factor. OAuth is the mechanism with which a third party (a “client” or “App”) can be delegated a level of authority on an account (the “first party”, most commonly you) with an OAuth provider (the “second party”). This usually includes allowing an app… Continue reading Thou Shalt Not Use OAuth

A Flask Mega-Tutorial: Intermezzo I

I’ve planned to tell you more about Flask. I’ve mentioned this is an application in development, and I was following my own learning curve. I have to admit I’ve outpaced my learning curve mega-tutorial series, slightly. I was planning on maybe posting one part of the mega tutorial about every week or so, but I’m… Continue reading A Flask Mega-Tutorial: Intermezzo I
