I choose to use \"Jenkins\'s own user database\" security realm for user login as I couldn\'t use LDAP in my company. And Google\'s OpenID has issue when you decided to change
I installed the Role plugin under Jenkins-3.5, but it does not show the "Manage Roles" option under "Manage Jenkins", and when one follows the security install page from the wiki, all users are locked out instantly. I had to manually shutdown Jenkins on the server, restore the correct configuration settings (/me is happy to do proper backups) and restart Jenkins.
I didn't have high hopes, as that plugin was last updated in 2011
