+===== シンボルリンクを辿る設定 =====
+^  設定項目  ^  意味  ^
+| ''follow symlinks''  | シンボリックリンクをフォロー（追跡）するかを制御。''yes'' でリンクをたどる。デフォルトは ''yes''。  |
+| ''wide links''  | 共有ディレクトリ外へのシンボリックリンクを許可。''yes'' で外部リンクをたどる。デフォルトは ''no''。  |
+| ''unix extensions''  | Unix特有の機能（シンボリックリンク、権限、UID/GID）を有効化。''yes'' で有効。デフォルトは ''yes''。  |
+| ''allow insecure wide links''  | Samba 4.13以降で追加。''wide links = yes'' を強制的に有効化するが、セキュリティリスクが高い。デフォルトは ''no''。  |
+===== トラブルシューティング =====
