Comment 1 for bug 1894132

I had this one as well as the following:

sssd_check_socket_activated_responders[111869]: The nss responder has been configured to be socket-activated but it's still mentioned in the services' line in /etc/sssd/sssd.conf.

After addressing the second one according to https://sssd.io/docs/design_pages/socket_activatable_responders.html by removing the services line from sssd.conf, the complaints about sssd_sudo.log were gone as well.

HTH!
