AWS res documentation change

Service: res · 2025-09-28 · Documentation low

File: res/archive/release-minus-1/ug/active-directory-sync.md

Summary

Updated image alt texts, added details about SSSD configuration parameters (enumerate and ldap_id_mapping), and fixed log group path formatting

Security assessment

Added documentation about SSSD parameters like 'enumerate' and 'ldap_id_mapping' which relate to directory service security configurations. While these settings impact security posture (e.g., caching user data, ID mapping compatibility), there's no evidence of addressing a specific vulnerability.

+Some common custom SSSD settings are:
+
+  * `enumerate` \- Set to 'true' to cache all user and group entries from the directory service. Disabling this could add a short delay to users' first login.
+
+  * `ldap_id_mapping` \- Set to 'true' to map LDAP/AD user and group IDs to local UIDs and GIDs on the Linux system. Enabling this can improve compatibility with existing POSIX scripts and applications.
