Jenkins Github Authentication error: user is missing the Overall/Read permission

Task:

Access Denied

<user> is missing the Overall/Read permission

Solution:

This is how I resolved the authentication problem:

1.  Edit config.xml file, e.g.

2.  sudo vi /var/lib/jenkins/config.xml

1.  Change useSecurity element's value to false, e.g.

2.  <useSecurity>false</useSecurity>

3.  Remove authorizationStrategy block

3.  Restart Jenkins: /etc/init.d/jenkins restart.

4.  Access Jenkins through URL as usual and reconfigure security again.
