🚀 How to Deploy Keycloak on Ub...

Von 2005 bis 2011 habe ich bei Microsoft mitgeholfen, den Käfig zu bauen.

Nicht die Produkte. Die Wörter.

„Tenant". „App-Registrierung". „Verzeichnisrolle." Vokabular war dort nie ein Nebenprodukt, es war Strategie. Wer die Begriffe setzt, mit denen eine Branche denkt, muss seine Produkte nicht mehr verteidigen, die Konkurrenz muss in einer Fremdsprache antworten. Der MCSE war kein Wissensnachweis, er war ein Sprachkurs mit Urkunde. Heute heißt er SC-300 und tut exakt dasselbe.

Es funktioniert bis heute. Es funktionierte sogar bei mir.
Letzten Samstag saß ich vor Keycloak für die Isar Open Source Community und verstand kein Wort. Realm? Client? Protocol Mapper? Zwei Stunden später fiel der Groschen, und er fiel unangenehm laut:

Ich kannte das alles. Seit zwanzig Jahren. Nur unter anderen Namen.
Ein Realm ist ein Tenant. Ein Client ist eine App-Registrierung. Rollen sind Rollen. Claims sind Claims.

Deshalb ist „der Wechsel weg von Entra ist zu komplex" keine Analyse. Es ist eine Ausrede, die sich als Sachverstand tarnt. Es fehlt kein Know-how. Es fehlen zwei Seiten Übersetzung.
Ein Käfig aus Wörtern hält nur so lange, wie man das Wörterbuch nicht liest.

CVE-2026-14781 (MEDIUM): Red Hat Build of Keycloak flaw in OIDC broker email_verified claim sync. If trustEmail=true & userinfo enabled, attacker can mark emails as verified. Review config & monitor fixes. https://radar.offseq.com/threat/cve-2026-14781-improper-validation-of-consistency--d19be74f7ead5808 #OffSeq #Keycloak #Vuln #IAM

Hab halt deren compose files in mein bestehendes Setup adaptiert. Eine Unzahl von ENB-Variablen deren Default direkt im Compose-File definiert sind, container Namen die in anderen Konfigurationen gesucht/ersetzt werden müssen, wenn man sie ändert.

Und dann bin ich mir immer noch unsicher, brauch ich jetzt nen #Keycloak + Datenbank? 🤨
Und den #LDAP? 🤔
Oder was davon ist für ein Prod-Setup mit ner Handvoll Nutzer optional? 😵‍💫

@bert_hubert I'm the last owl to take the side of big tech, but just saying, have you ever personally tried integrating oauth2/webauthn/OIDC/SSO into various #OpenSource web services? No? I want to wish you all the best of luck with that, as you roll out your enterprise-scale OpenSource deployments.

I think there's good reason all these big organizations with valiant intentions of escaping big tech, end up crawling back to big tech. The OpenSource SSO offerings leave something to be desired. Where is the realistic competitor to #Microsoft Entra? Would that be #KeyCloak? #Authelia?

It's much harder than you think.

After trying #Keycloak for a while - trying to integrate it with ForgeJo for Single-Sign-On (#SSO), I wasn't really satisfied with Keycloak. Keycloak's error messages were too unhelpful. The documentation, too nebulous. I lurked in their forums a bit, but didn't really want to use Slack as some sort of depended-upon service. Whatever the Keycloak error messages said, the eventual solutions usually ended up being so disconnected with the error message, that it dawned on me that the Error messages were effectively "Red Herrings" - served only to throw me off the trail.

Keycloak had a vibe to it that I'd describe as "Enterprise Bozak". It had the *look* of professionalism - making a solid effort to *appear* attractive to higher-up management types - but it didn't really *deliver* the helpfulness I was expecting, to actually overcome technical hurdles encountered. I've set Keycloak aside for now, and I'm trying out #Authelia instead, with an LLDAP backend. They seem easier to work with, as the error messages were good so far: had more of a technical helpfulness. After several hours of tinkering, I've set up my first LLDAP/Authelia users, including registering a passkey. I'll next see if I can integrate the Authelia SSO to #ForgeJo.
