SharePoint Online hub sites namespace and structure

For my company’s upcoming intranet based on SharePoint Online (SPO), we’ve looked into ways to organize our sites.

We’ll be using SharePoint Online as platform for our upcoming intranet. As Microsoft currently doesn’t support much visual tweaking, we were looking to apply our own CSS to the intranet related SPO sites. Applying Custom CSS is not supported, so we were looking for a workaround until Microsoft hopefully does enable this in the future. Although not supported, and likely not even recommended, we got our custom CSS up and running by creating an application customizer, based on the official…

Our Jenkins CI server (https://jenkins.company.com) doesn’t have access to Internet (neither directly nor through a proxy), yet we need to update both Jenkins itself as well as the Jenkins plugins. We’ve set up another of our servers, https://jenkins-repo.company.com, as a Jenkins mirror site, which on a regular basis runs this command in a cron job: The /srv/mirrors/jenkins folder is hosted by Nginx. As the rsync’ed files contain references to https://updates.jenkins.io, Jenkins will try and contact https://updates.jenkins.io when downloading the updated…

A while back I started working at an IT department that didn’t really have must in-house development, and thus didn’t have any integration architecture defined. I set out to look into our business needs along with potential architectures. I’d been a great fan of message based, event driven architecture, and found that to be a good fit for our needs. One of my first projects was quite simple – the user would visit one of our internal websites and submit…

Currently, I’m developing the business logic for creating the new sites, including setting the correct permissions, theme, links and so forth. I’m using Visual Studio for this project. I’m new to both SharePoint Online as .NET, and as tutorials on setting up Visual Studio with regards to SharePoint Online provisioning seems to be lacking, I…

Modifying cn=config in OpenLDAP without rootDN password

Using a configures “admin” user and the corresponding password, I successfully created a bind user uid=bind_user,ou=users,dc=work,dc=com on an OpenLDAP server. The bind user needed escalated privileges, but as the cn=admin,dc=work,dc=com user didn’t have write access to the cn=config database, all my efforts running commands such as ldapmodify on the bind user, resulted in this error message: I didn’t have access to the rootDN password, so I was kind of stuck for a while. Then I was advised to try ldapvi,…
