Jeremy Fontenot / Technical portfolio
Practical administration. Documented results. Original technical evidence.
Investigate Linux domain-authentication behavior and retain separate Windows client validation. Technologies: Ubuntu, SSSD, systemd, SSH, Windows, Active Directory, DNS, and DHCP.
The Linux01 derivative documents direct responder activation, conflicting NSS/PAM/PAC sockets, and a rejected config_file_version directive. The separate WS01 derivative records domain membership, network configuration, and a successful secure channel.
The Linux record describes removing the rejected directive, disabling conflicting sockets, restarting SSSD, and clearing failed-unit state. Post-remediation checks report zero failed units, passing configuration validation, AD identity lookup, and a new AD-authenticated SSH session. These findings apply to Linux01; they do not establish all cross-platform authentication paths.
Supporting portfolio project, not a claim of enterprise fleet ownership. Individual platform claims remain bounded by their underlying evidence.
Registry status retained in the audit: COMPLETE . Evidence below is assessed by artifact type; this package does not rerun the lab.
Retained Linux01 evidence documents an SSSD responder/socket conflict correction and successful post-remediation AD identity lookup and SSH.
