When I open Qubes Global Config window, such error messages appear in dom0 terminal (journalctl -f was used to watch logs):
(Both start from “sudo” then go numbers in square brackets) PAM adding faulty module: /usr/lib64/security/pam_sss.so
PAM unable to dlopen(/usr/lib64/security/pam_sss.so): /usr/lib64/security/pam_sss.so: невозможно открыть разделяемый объектный файл: Нет такого файла или каталога
(can be translated as: “Cannot open shared object file: No such file or directory”)
And then after few messages the first error message appears again. This scheme always the same: these two messages, then first one repeats itself.
Since these messages contain word “security” I decided to show it here.
