I\'m using the github oauth plugin for our logins but for all of our users in the Organisation I get an error:
Access Denied
is missing the Ov
Fix it by these 2 shell commands on the server (sudo permission is required):
sudo ex +g/useSecurity/d +g/authorizationStrategy/d -scwq /var/lib/jenkins/config.xml
sudo /etc/init.d/jenkins restart
This will remove useSecurity and authorizationStrategy lines from your config file.
