RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Type: Enhancement
Doc Text:
.Security classification banners at login and in the desktop session You can now configure classification banners to state the overall security classification level of the system. This is useful for deployments where the user must be aware of the security classification level of the system that they are logged into. The classification banners can appear in the following contexts, depending on your configuration: * Within the running session * On the lock screen * On the login screen The classification banners can take the form of either a notification that you can dismiss, or a permanent banner. For more information, see link:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/using_the_desktop_environment_in_rhel_8/assembly_displaying-the-system-security-classification_using-the-desktop-environment-in-rhel-8[Displaying the system security classification].

Comment 1 Michael Boisvert 2021-12-15 18:33:53 UTC 
Using gnome-shell-extensions-40.5-4.el9, you can easily program a classification banner within the running session, lock screen and the login screen.

To create a banner in the session and lock screen simply install the extension then customize the extension using one of the many ways, it works perfectly using the Extensions Flatpak.

To create an orange bottom only banner with white text on the login screen do the following (obviously this can be tailored by the user):

1. Install gnome-shell-extension-classification-banner-40.5-4.el9 and gnome-shell-40.7-1.el9
2. Create file called /etc/dconf/db/gdm.d/99-class-banner

[org/gnome/shell]
enabled-extensions=['classification-banner.github.com']

[org/gnome/shell/extensions/classification-banner]
background-color='rgba(255,103,31,0.75)'
message='TOP SECRET'
top-banner=false
bottom-banner=true
system-info=false
color='#fff'

3. dconf update as root
4. reboot
