• Tracing which identity source answers for a user: getent, id, nsswitch.conf and sss_cache

  When a Linux host is joined to a directory, a user lookup can be answered by local files, SSSD/LDAP, or another module entirely, in the order nsswitch.conf lists them. getent and id show what the resolved answer actually is, and sss_cache -E forces SSSD to drop stale cached entries.
