User listing is the same as in SDDM, so the account is listed correctly. Logs indicate that pam_sss (which appears to be used for AD) succesfully authenticates: Jan 26 09:35:19 plasmalogin-helper[6868]: pam_sss(plasmalogin:auth): authentication success; logname= uid=0 euid=0 tty= ruser= rhost= user=jgamao but later fails: Jan 26 09:35:19 plasmalogin-helper[6868]: pam_sss(plasmalogin:account): Access denied for user jgamao: 6 (Permission denied) The logs are full of sssd-pam failing. This is probably the root cause due to some misconfiguration. SDDM does not get a permission denied message. Maybe somewhere plasmalogin needs to be whitelisted to allow login?
(In reply to Oliver Beard from comment #4) > Maybe somewhere plasmalogin needs to be whitelisted to allow login? If there's a spot to do that, I dunno where it'd be. I never had to make any whitelisting when I use LightDM or GDM or SDDM on other thin clients in the company (they're Kubuntu, Ubuntu Cinnamon and regular Ubuntu), or even when I setup my Neon workstation.
