Top 6 Open Source Identity and Access Management (IAM) Solutions For Enterprises
KeyCloak is a Cloud Native Computing Foundation (CNCF) project that offers enterprise IAM solutions. Keycloak emphasizes proficient enterprise authorization solutions by providing:
-
Outline: Self hostable, realtime, Markdown compatible knowledge base
Outline only uses SSO for authentication. The solution when self hosting is use a private keycloak server [1]. This allows you to do email based auth.
-
Keycloak open redirect: wildcard redirect URIs can be exploited to steal tokens
> Keycloak was good but has too much legacy for 10+ years.
I got curious, actually seems to check out and explains why it's so well documented (but also complex and oftentimes confusing):
> The first production release of Keycloak was in September 2014, with development having started about a year earlier.

What Is OIDC?
> Don't outsource either your authentication or authorization. Run it in-house.
This is hard to do, though. I hope people here will drop a lot of combinations that work for them!
Personally, for a small/medium scale project, I went with:
Keycloak: https://www.keycloak.org/
It supports various backing RDBMSes (like PostgreSQL, MariaDB/MySQL and others), allows both users that you persist in your own DB, as well as various external sources, like social login across various platforms, is an absolute pain to configure and sometimes acts in stupid ways behind a reverse proxy, but has most of the features that you might ever want, which sadly comes coupled with some complexity and an enterprise feeling.
I quite like that it offers the login/registration views that you need with redirects, as well as user management, storing roles/permissions and other custom attributes. It's on par with what you'd expect and should serve you nicely.
mod_auth_openidc: https://github.com/OpenIDC/mod_auth_openidc
This one's a certified OpenID Connect Relying Party implementation for... Apache2/httpd.
Some might worry about the performance and there are other options out there (like a module for OpenResty, which is built on top of Nginx), but when coupled with mod_md Apache makes for a great reverse proxy/ingress for my personal needs.
The benefit here is that I don't need 10 different implementations for each service/back end language that's used, I can outsource the heavy lifting to mod_auth_openidc (protected paths, needed roles/permissions, redirect URLs, token renewal and other things) and just read a few trusted headers behind the reverse proxy if further checks are needed, which is easy in all technologies.
That said, the configuration there is also hard and annoying to do, as is working with OpenID Connect in general, even though you can kind of understand why that complexity is inherent. Here's a link with some certified implementations, by the way: https://openid.net/developers/certified-openid-connect-imple...

Auth0 increases price by 300%
You couldn't pay me to use their bullshit...if you need an identity server/provider go with Keycloak. Open source, free, and standards based, works better and scales better too.

BuildKit in depth: Docker's build engine explained
and its "oh, you want multi-arch, do you?" friend. While prosecuting this <https://gitlab.com/gitlab-org/gitlab/-/issues/339567> I learned that https://hub.docker.com/layers/multiarch/qemu-user-static/7.2... actually mutates the binfmt_misc in buildx's context in order to exec the static copy of qemu in it https://github.com/multiarch/qemu-user-static/blob/v7.2.0-1/...
and, that the buildx plugin itself has some qemu magick in it, which got addressed in a minor version bump but I couldn't track down the relevant GitHub issue this second (I've flushed it from my mind, only recalling that there were a lot of actors in that tire fire)

Gitlab password reset bug leaves more than 5.3K servers up for grabs
For folks who wanna see what led to this exploit in a Rails codebase, hereβs the commit where the exploit is fixed:
https://gitlab.com/gitlab-org/gitlab/-/commit/c571840ba2f0e9...
> "RecoverableByAnyEmail"
Added 8 months ago [1]. And then one month later:
> "password_reset_any_verified_email"
Was removed. 7 months ago [2], *note* __verified__ word here.
No blaming or conspiracy intended in this post, just listing links to relevant commits.

2 - https://gitlab.com/gitlab-org/gitlab/-/commit/a935d28f3decf8...
This doesn't look like the actual fix but rather a follow-up refactor. I believe the fix is here: https://gitlab.com/gitlab-org/gitlab/-/commit/abe79e4ec43798...
- recoverable.send_reset_password_instructions(to: email) if recoverable&.persisted?
This is actually a follow-up refactor, the fix is here: https://gitlab.com/gitlab-org/gitlab/-/commit/abe79e4ec43798...

Geany 2.0 Is Out
> ruby has just RubyMine which doesn't have a community edition and also isn't very good
I have a great deal of sympathy for RubyMine (and shudder at working for the CLion team, whew) because Ruby isn't doing the IDE author any favors. Given:
https://gitlab.com/gitlab-org/gitlab/-/blob/v16.5.0-ee/lib/g...
- what types are client_email and private_key? they are whatever type they're called with lolol
- the symbol Google::Auth::ServiceAccountCredentials just materializes; was it required in some containing context and thus is in scope by _this_ required file? are those symbols visible in every context from one of the various Gemfile lines? a hard-core rubyist knows
- where did the symbol StringIO come from? well, from require 'stringio' obviously, which is on .. err, which line exactly? I guess that lends weight to the 'this file is obviously running as a child context of some other file' theory
I think half of it is the culture of Rubyists and half of it is "productivity hacks" of "if it runs, then it must be correct"
I also recognize that I'm very clearly a static typing snob, and firmly in the camp of "please import symbols you use," but that doesn't stop me from having a great deal of sympathy for anyone who has to implement an IDE for such a monkey-patch friendly language

GitHub and Developer Ecosystem Control
BitBucket and GitLab both have organizational backing, BitBucket even more so. GitLab does offer an open source core for those to self host. Though I must say the "Contact Sales" link at the top navigation banner is quite interesting. The GNU project does offer hosting services, though it's very much conditional on buying into their philosophy. There are also some options of hosted software such as heptapod and Codeberg.

π¦ GitLab CI: 10+ Best Practices to Avoid Widespread Anti-patterns
The "needs" keyword can also be applied to jobs within the same stage, allowing you to create stageless pipelines similar to those in Jenkins. However, it's important to note that in reality, jobs fall into the default stage, which is Test. This limitation is currently being addressed in GitLab, as mentioned in this issue.
