At the moment I’m working with a customer to secure all traffic in HCL Connections. The target is to have only encrypted network traffic between servers.

Today I started enabling encryption to Redis. This is a documented process , but the documentation is outdated and incomplete.

Today I read the article KB0118248 and remembered my blog post from 2018 . I also checked the attached aha idea where a comment states that you can use iframe for Youtube. Despite what KB0118248 incorrectly states, it is absolutely possible to embed videos in HCL Connections blogs and wikis using the HTML video tag as demonstrated in this post.

The HCL Connections documentation describes the process for configuring Windows desktop single-sign-on in a somewhat complicated way. Here are the necessary steps for setting up with the highest possible encryption.

I received several complaints from users who struggle to identify uploaded images in the File Uploads section of blogs. This happens because pasted images get cryptic filenames like editor_image_ + UUID, making it challenging to identify and delete unused images.

I use chezmoi for my dotfiles. To find out why and how to get started, check out my talk from Chemnitzer Linuxtage 2025 .

Within chezmoi, you can use the file .chezmoiexternal.toml to download archives or git repositories during updates. This is particularly useful for managing external dependencies. Let me walk you through some common use cases.

I haven’t touched the Connections scripts for a long time, but I recently made some minor updates to fix compatibility issues with newer versions and added small scripts to speed up configuration. I also got the documentation script running from the menu.

Most of the LDAP connections from IBM WebSphere Application Server are configured with TLS. So you need to have the root certificate in the WebSphere truststore to connect.

For HCL Connections 8 CR9, it is mandatory to update MongoDB to version 7. During my first migrations, I encountered some issues and would like to provide workarounds and additional troubleshooting tips to help others with this process.

In late 2023, I started exploring immutable operating systems, specifically Fedora Silverblue and Bluefin . If you’re curious about why I made this switch and want more technical details, check out my Froscon Talk on ‘Next-Gen Desktops’ or watch the video presentation below.

I attended Chemnitzer Linuxtage 2025 from Friday, March 21st to Sunday, March 23rd. It was my second time at the event, and I enjoyed it even more than last year. This time, approximately 3,500 people attended in person, with up to 250 parallel viewers joining the live streaming of lectures. You can find more details in the official blog post .

The last weeks I had twice the issue of a huge homepage database with HCL Connections. Both systems weren’t installed by me, but I reviewed them.

So I know this issues quite well since I faced it the first time years ago. This always happens when you migrate Connections environments side-by-side, and you forget to remove the old search nodes.

I had some issues with PDF export functionality in HCL Connections the last weeks.

The server became unresponsive multiple times due to high load from PDF exports. To quickly address the issue, the simplest solution is to disable the PDF export feature by configuring the icxt.pdfexport.access.requiredrole property in the Resource Environment Entries.
