I’m trying to use DUO in my Redhat 6.8 - Gnome GUI. When I lock Gnome and log in back, it doesn’t use pam_duo.so at all (since there’s no log saying success or failed, neither connection to DUO was made). I found this in log /var/log/message:
gnome-screensaver-dialog: Couldn’t open /etc/duo/pam_duo.conf: Permission denied
Don’t know why this one has permission denied, while SSH/sudo work perfectly. pam_duo.conf has mod 400 since installation.
What can I do ?

Our previous testing KDM and GDM in RHEL 6 showed it appears to just simply not allow interactive prompting on the login and screen lock pages. We did test with LightDM on RHEL 6 and successfully saw the interactive login prompt. It also works with GDM on RHEL 7+.
Simply changing permissions on the pam_duo.conf won’t help, as Duo Unix expects the conf file to be secured (as does SSH), and will report issues if you were to open it up to group read.

This doesn’t work on Ubuntu 22.04 either. Anyone have an idea on how to fix it?
