*** ALL SESSIONS ARE PRESENTED IN DUTCH ***

Donderdag 25 juni 2026 zijn we te gast bij Inspark in Amstelveen.

We hebben weer een paar mooie sessies op het programma, waaronder een sessie van Derk van der Woude over Agent 365 en Agent ID. Ook geven we graag het podium aan Richard van der Els met zijn sessie over Cloud PKI en Entra CBA. Samantha gaat ons meenemen in alles wat komt kijken bij het opzetten van een centrale Entra ID tenant voor B2B gebruik.

Uiteraard praten we je weer bij over de laatste features binnen Entra in onze lightning-sessie. Riemen vast!

Deze avond zullen de sessies in het Nederlands worden gegeven.

PROGRAMMA

17.00 - 18.00 Inloop & Eten

18.00 - 18:20 Welkom door onze host, Inspark.

Lightning talk - What's new in Entra? Een korte sessie door Jan, Pim, Michel of Stefan over de laatste features binnen Entra. Zo zijn jullie weer helemaal bij!

18.20 - 19.20 Eén Entra ID tenant, meerdere organisaties: de architectuur achter de samenwerking
– Samantha Kloos-Kilkens

Netbeheerders in Nederland zijn geen concurrenten. Ze beheren samen de kritieke infrastructuur van het land en moeten steeds vaker nauw kunnen samenwerken. Toen de vraag kwam om een gedeelde Microsoft Entra ID tenant op te zetten waar meerdere organisaties veilig samen kunnen opereren, bleek al snel dat de standaardaanpak voor B2B hier niet volstaat.

In deze sessie loop ik door de architectuur en de securitybeslissingen van deze omgeving. Access governance, authenticatie en tenant hardening zijn ontworpen voor een omgeving die geen enkele organisatie in z'n eentje bezit.
We kijken hoe je users binnenkrijgt, hoe je gedelegeerd beheer organiseert met Administrative Units, hoe Conditional Access eruit ziet met meerdere doelgroepen en verschillende vertrouwensniveaus, welke MFA claims je van welke tenant wel of niet vertrouwt, en wat tenant hardening betekent wanneer samenwerken net zo belangrijk is als security.

Voor iedereen die identity architectuur ontwerpt waar meerdere organisaties één tenant delen, en waar security geen bijzaak mag zijn.

19.20 - 19.30 Korte pauze

19.30 - 20.00 Cloud PKI and certificated-based authentication - Richard van der Els

The benefits of Cloud PKI how to setup and how to use it.

In deze presentatie neem ik jullie mee in hoe makkelijk je Cloud PKI opzet je de certificaten kunt distribueren en deze vervolgens ook kunt gebruiken om jezelf te authenticeren.

20.00 - 20.20 Pauze

20.20 - 21.20 Agent 365 Security from an Entra perspective

• Derk van der Woude

AI-agents zijn niet meer weg te denken uit de moderne werkplek. Microsoft 365 Copilot, autonome agents, geautomatiseerde workflows — ze schieten als paddenstoelen uit de grond. Maar wie beheert en beveiligt al die digitale collega's eigenlijk?
In deze sessie duiken we diep in het Entra Agent ID-platform: de plek waar Microsoft identiteitsbeheer voor AI-agents samenbrengt. We beginnen met de fundamenten — wat is een Agent ID, hoe werkt het platform, en welke beveiligingsbasisprincipes gelden er voor niet-menselijke identiteiten?

Daarna gaan we écht de diepte in. Want agents zijn net mensen: ze hebben toegang, ze maken fouten, en ze kunnen misbruikt worden. We bekijken hoe ID Protection risicovolle agentgedrag detecteert, hoe je met Conditional Access granulair toegangsbeleid afdwingt voor agents, hoe Identity Governance zorgt dat agents alleen krijgen wat ze nodig hebben — en niet meer — en hoe Secure Access de verbindingen van agents naar resources beschermt.

Na deze sessie ga je naar huis met een helder beeld van het Entra-beveiligingslandschap voor agents, concrete handvatten om je eigen agentomgeving te beveiligen, en misschien een gezonde dosis paranoia over alles wat er al rondloopt in jouw tenant.

21.05 - 22.15 Ruimte om gezellig bij te kletsen onder het genot van een hapje/drankje.

Dear all,

With summer just around the corner, we are happy to invite you to the Summer Edition of the PostgreSQL User Group NL Meetup on June 25th 2026 in Amsterdam.

This time we have been invited by Databricks to host the event in their Amsterdam headquarters. We are very appreciative of this gesture and we like to thank them for supporting the PostgreSQL community with the venue and the hospitality.

On the agenda we have two PostgreSQL experts in their field. First up is an alumni presenter of the PostgreSQL User Group, Matthias van der Meent, who will be taking us on a deep dive into one of the better known index types: GiST. Next on the program is Bart Orbons, who will centre his presentation around grouping.

As usual, we have reserved some space in the program for anyone who wants to do a lightning talk. If you are interested, please contact us via a personal message on meetup.com.

We are very grateful for the contributions of both presenters as well as our host, to make this all possible for the PostgreSQL community in the Netherlands.

We hope to meet many of you at the meetup — a moment where PostgreSQL users can connect, share knowledge, and discuss the latest developments in the PostgreSQL ecosystem.

We look forward to a great meetup!
Feike Steenbergen Gerard Zuidweg

Meetup Program
17:30 – 18:25 — Welcome, Beer & Bites 18:25

18:30 — Opening

18:30 – 19:10 — GiST indexes: An analysis – Matthias van der Meent
Abstract: PostgreSQL has various index types, each supporting different query patterns and behaviours. In this talk, Matthias will go over one of the better known index types: GiST — how and where it is used, how it works, its strengths, its weaknesses, and some possible improvements.
About Matthias: Matthias van der Meent is a PostgreSQL hacker and contributor with over 5 years of contributions to the project. His focus is mostly on subsystem performance, indexing, and resource usage.

— (Very) Short Break —

19:15 – 19:55 — 'Grouping, the way you want it' – Bart Orbons
Abstract: This talk dives into PostgreSQL's advanced grouping features, showing how to go beyond a plain GROUP BY to aggregate data exactly the way you need it. Expect practical examples that make complex reporting queries simpler and more powerful.
About Bart: PostgreSQL user and enthusiast. Started using PostgreSQL in 2000 and has not stopped since — having worked before with Sybase and Oracle, but not anymore. Until four years ago, Bart worked at XS4ALL Internet as a technical software architect focused on database and software modelling, until the company was folded into its parent organisation. He then helped migrate the customer base into their systems before moving on to his current role at Z-CERT, where he helps set up company administration and systems. A regular at pgconf.eu, this talk is part of a series Bart originally created for colleagues at XS4ALL to improve their SQL skills and introduce newer features of the SQL language.

19:55 – 20:00 — Lightning Talks

20:00 – 20:30 — Wrap-up and drinks

Schedule
19:00 Walk-in
19:15 David Beentjes on NativePHP Mobile
19:55 Break
20:15 Daniele Besana on Running a WooCommerce store: the good, the bad and the ugly
20:45 Open Call 🔔
21:00 Drinks @ the bar

Did you ever receive an offer to build a mobile app but had to decline because you didn't have the knowledge in the needed programming languages? Well, maybe now you do have the required skills. In his talk on NativePHP Mobile, David Beentjes (12+ years of WordPress development experience and co-owner of Unloc) shares his insights from building an Android and iOS app in the same programming language WordPress is written in: PHP. Based on a real-world app, he showcases the possibilities that NativePHP unlocks for WP builders and how an app can be integrated with an existing WordPress site for authentication, content management, or whatever else you can think of.

Daniele Besana is the founder of WP-OK. In 2023, together with his wife Hanny, he acquired a 6-figure webshop at cafe-analog.nl. Coming from years of supporting ecommerce clients, running a store firsthand gave him a completely new perspective on the real challenges behind a WooCommerce business.
In this talk, Daniele shares the lessons learned after taking over an existing webshop: what they improved, what surprised them, what mistakes they made, and the many non-technical aspects such as logistics, suppliers, inventory, and (some) marketing.
This is not a technical WooCommerce talk, but a practical and honest look at what it really means to run an online store: the good, the bad and the ugly.

Meetup – Comparing SEDI and the KERI Protocol with the eIDAS-based EUDI Wallet Model
(KERISuite: Free Open-source Identifier Systems Software under TrustoverIP Foundation that is anchored in LFDT)

Monday June 29, 7:00 PM
Amsterdam area (exact location to be announced)
A meetup about SEDI and its supporting KERI protocol, and how this compares to the EUDI Wallet (eIDAS-based) that will be introduced across Europe.

• SEDI = Model legislated in the State of Utah (US): State-Endorsed Digital Identity. The state endorses a digital identity, while the citizen remains in control.
• KERISuite = technical foundation for secure, self-controlled, persistent, cryptographically verifiable digital identity.
• eIDAS = European legal framework for electronic identification and trust services.
• EUDI Wallet = the European Digital Identity Wallet under eIDAS 2.0, enabling citizens and organizations to store and share digital credentials.

SEDI and eIDAS/EUDI represent two policy approaches to digital identity: Some US states versus EU.

KERI/KERISuite can be seen as a possible technical infrastructure for implementing such models in a privacy-preserving, decentralized, and verifiable manner.
SEDI places more emphasis on individual sovereignty and state endorsement, while eIDAS/EUDI focuses more on EU-wide interoperability and legal recognition.

There are also concerns about the level of trust European citizens are expected to place in these systems.

The meetup is organized by the Permissionless Society Meetup Group and supported by the Linux Foundation Decentralized Trust (LFDT).

• Introduction to SEDI and the KERI protocol — Henk van Cann
• Presentation on the characteristics of eIDAS/EUDI from that perspective - {Speaker to be announced soon}

Free entrance.
Doors open at 6:45 PM.

The meetup starts exactly at 7:00 PM. At 8:30 PM we'll have a drink and a chat.

Also announced here: https://www.meetup.com/lfdt-netherlands/events/314921548

Meetup – SEDI en het KERI-protocol vergelijken met het eIDAS-gebaseerde EUID.

Maandag 29 juni, 19:00 uur
Omgeving Amsterdam (locatie volgt)

Een meetup over SEDI en het ondersteunende KERI-protocol en hoe dit zich verhoudt tot de EUID-wallet (eIDAS-gebaseerd) die we in Europa gaan krijgen.

Kort:
SEDI = State-Endorsed Digital Identity, wettelijk vastgelegd in de staat Utah (US). De staat “endorses” een digitale identiteit, maar de burger blijft zelf de identity provider.
KERISuite / KERI = technische basislaag voor veilige, zelfbeheerde, lang houdbare, cryptografisch verifieerbare digitale identiteit.

eIDAS = Europees juridisch kader voor elektronische identificatie en vertrouwensdiensten.

EUDI Wallet = de Europese digitale identiteitswallet onder eIDAS 2.0, waarmee burgers en organisaties digitale credentials kunnen bewaren en delen.

Samenhang:
SEDI en eIDAS/EUDI zijn twee beleidsmodellen voor digitale identiteit: VS versus EU. KERI/KERISuite kan worden gezien als een mogelijke technische infrastructuur om zulke modellen privacyvriendelijk, decentraal en verifieerbaar uit te voeren. SEDI legt meer nadruk op individuele soevereiniteit en de staat die goedkeurende ondersteuning geeft; eIDAS/EUDI legt meer nadruk op EU-brede interoperabiliteit en wettelijke erkenning. Er zijn zorgen over het vertrouwen dat Europese ingezetenen moeten hebben in dit systeem.

De meetup wordt georganiseerd door Permissionless Society Meetup Group en ondersteund door de Linux Foundation Decentralized Trust (LFDT).

Er zijn twee sprekers:
Een introductie over SEDI en het KERI-protocol - Henk van Cann
Een presentatie over de karakteristieken van eIDAS in dat perspectief - Spreker weldra aan te kondigen

Toegang is gratis. Deur open om 18:45 uur. Het begint precies om 19:00 uur.
Om 20:30 uur uiterlijk napraten met een borrel.
