I install plugin and configure admin user. It works fine.
But when I restart Jenkins, admin users keep having admin role but admin stuffs not accessible, I get an access denied error.
I get the same problem with any other configured user. Users keeping their roles in config but Jenkins (the plugin) doesn't give access to any role.
User are managed using : "Jenkins Own User Database"
In other to make it work, I need to kill Jenkins, delete config.xml file and restart it again with new configuration.
With version 3.0, Jenkins fails to start.
Thank you for helping.
