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
What I did when I got this error is to edit config.xml as mentionned by other users and correctly re-add my username in LOWERCASE in "configureSecurity" Jenkins' page. I was using "KrustyHack" when adding permissions but it didn't work. I had to add "krustyhack" instead, and it worked.
I hope it helps.
