I was helping a team at work recently and we needed to add a few users to Jenkins. We added the users and then asked them to login and make sure they could run jobs. 2 out of 3 people were able to run jobs, but the 3rd person was not. We had added them the same as everyone else, but it wasn’t working. I had them logout and back in and that’s when I realized the issue -
Jenkins is case sensitive If you add a user as
mrbusche but they login as
MRBUSCHE they’re not recognized in Jenkins.
Long story short
