Welcome @stoeps.de, the blog of Christoph Stoettner

I work at Vegard IT GmbH as a senior consultant with a focus on collaboration software, Kubernetes, security and automation. I mainly deal with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform and Linux.

Sometimes my daily work results in technical talks and blog articles, which you can follow here more or less regularly. You can find the presentations in the main menu under public speaking .

I created a list of tools I use regularly, most of which have been released under an open source license.

In my spare time I read a lot, test all kinds of technical software and gadgets and try to follow about 200 RSS feeds.
Here you can find a collection of them.

This is my private blog, all opinions are my own.

I had one Connections’ environment that I wanted to switch from OpenLDAP to Active Directory LDAP. The old OpenLDAP environment used LDAPS to connect, and so I assumed that the change was done quickly.

The first step was to make a copy of the tdisol folder I used for OpenLDAP and start changing the configuration files for the new LDAP server.

The official documentation, “Migrating data from MongoDB 3 to 5”, wants to dump the MongoDB databases in 3.6 and then restore this data into the newly deployed MongoDB 5.

On the other side, the helm chart providing MongoDB 5 can’t be installed on those old Kubernetes versions. So the process to update is:
