Description of problem: Fresh installation of RHEL 7 beta x86_64, with only a single administrator user created and root password not set. After installation is finished I cannot use sudo, which after rescuing the system turns out to be because the rule in /etc/sudoers allowing members of %wheel to use sudo is still commented out Version-Release number of selected component (if applicable): sudo-1.8.6p7-7.el7.x86_64.rpm How reproducible: Always Steps to Reproduce: 1. Fresh install of RHEL 7 beta, with root password unset but an admin user defined 2. Boot the newly installed system 3. Log in and try to use sudo Actual results: Attempt fails, user not authorized. While user is in %wheel, the group is not authorized to use sudo Expected results: Attempt should succeed -- Additional info: In sudo 1.8.8-1 as shipped in Fedora 20 (and presumably whichever version is default in Fedora 19) the default is for %wheel to be able to use sudo with password
This got me as well. It appears to be intentional (see bug 969373). Just to confuse everyone, instead of using sudo we need to use pkexec on RHEL 7 by default.
