Automatically unlock gnome keyring at boot

I changed the file /etc/pam.d/lightdm:

[buckfae@buckfae-pc ~]$ sudo cat /etc/pam.d/lightdm
#%PAM-1.0
auth        include     system-login
auth        optional    pam_gnome_keyring.so
account     include     system-login
password    include     system-login
session     include     system-login
session     optional    pam_gnome_keyring.so auto_start

I assume that i had to remove the -?
It still does not work.

I can confirm that i’m using lightdm:

[buckfae@buckfae-pc ~]$ grep '/usr/s\?bin' /etc/systemd/system/display-manager.service
ExecStart=/usr/bin/lightdm
