That authentication module (pam_sss normally) will be usable by > users with uid >= 1000, but not by system user accounts. It appears that you're saying ssh as root would fail because of the UID >=1000 and pam_deny, but it works on my system, yet still gives that error (sometimes). Can I ask you to clarify how it relates to remote root access? Somehow remote ssh root access works on my system, so I don't understand which pam module would be denying access? Also, why are the UIDs hardcoded in pam.d files when there is /etc/login.defs? How does that file apply to this?
