I have a Raspberry Pi that I have connected to our AD domain using realm. It is using sssd-ad to perform user authentication.All accounts in the child domain to which the Pi is joined worked. However some accounts from the parent domain do not work, but some do work. So far all I am seeing is the following errors in /var/log/auth.log.Nov  3 14:13:03 pi-ncb234 lightdm: pam_sss(lightdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= user=user_name@domainNov  3 14:13:03 pi-ncb234 lightdm: pam_sss(lightdm:auth): received for user user_name@domain: 10 (User not known to the underlying authentication module)Are there any tools that will allow me to see how it is searching for user_name which does exist?Thanks
