Summary
The System Security Services Daemon (SSSD) service provides a set of daemons to manage access to remote directories and authentication mechanisms. It also provides the Name Service Switch (NSS) and the Pluggable Authentication Modules (PAM) interfaces toward the system, and a pluggable back-end system to connect to multiple different account sources.
Security Fix(es):
* sssd: sssd: IdP authentication prefix comparison allows cross-user impersonation (CVE-2026-87853)
Bug Fix(es) and Enhancement(s):
* [RFE] pam: Forward environment variables from PAM client to p11_child (JIRA:Rocky Linux-188425)
* Spurious warnings about `ldap_sudo_search_base` (JIRA:Rocky Linux-248164)
