What's your policy version? And did it perhaps fail during %post when it was updated - check yum.log? Does semodule -B fail? Might have to move aside your policy and reinstall it. > > > > [Cent-7:root@my_server home]# getsebool authlogin_yubikey > > authlogin_yubikey --> on > > --- > > > > The system accepts two-factor while the above is set to “on”. After some undetermined time (or immediately after a reboot) the Boolean toggles off. This can be confirmed since semanage shows that the default is still set to “off”: > > > > -- > > [Cent-7:root@my_server ~]# semanage boolean -l | grep "authlogin_yubikey" > > SELinux boolean State Default Description > > ... > > authlogin_yubikey (on , off) Allow authlogin to yubikey > > -- > > > > It looks similar to the following bug on Fedora: > > https://bugzilla.redhat.com/show_bug.cgi?id=1559174 > > > > _______________________________________________ > Selinux mailing list > Selinux@xxxxxxxxxxxxx > To unsubscribe, send email to Selinux-leave@xxxxxxxxxxxxx. > To get help, send an email containing "help" to Selinux-request@xxxxxxxxxxxxx. > _______________________________________________ Selinux mailing list Selinux@xxxxxxxxxxxxx To unsubscribe, send email to Selinux-leave@xxxxxxxxxxxxx.
