Resolution

If you see that message probably you had configured the Role Strategy Plugin as Authorization Strategy in the Configuration Security and later on has been replaced by CloudBees RBAC plugin.

The red message is due to you have set in the Jenkins global configuration the Restrict project naming property to Role-Based Strategy.

If you change this property to other value the issue will be solved.

A more aggresive solution is uninstall the Role Strategy Plugin, so Jenkins will ignore that piece of configuration.
