SSSD >= 2.10.1 no longer raises CAP_DAC_READ_SEARCH to effective in offline mode, so validate_tgt fails with EACCES reading /etc/krb5.keytab before the cached-credential fallback is reached. Adding krb5_validate = False disables the keytab validation step and restores reliable offline authentication for FreeIPA domain users. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
