Thank you very much for reporting this, Ryan.
Hello This bug is referring to Fedora 18 https://docs.fedoraproject.org/en-US/Fedora/18/html/System_Administrators_Guide/s1-users-configui.html I am sorry it is too late to fix that in that guide and these GUI descriptions are no longer in the System Admin Guide.
