In case the server supports the CIFS Unix Extensions, the client side (i. e. your side) attempts to set the effective UID and GID of the current process on newly created files, directories and devices. If this feature is turned off, the default UID and GID defined for the share will be used. It is recommended that you read the manual page of mount. cifs before you change this setting.
No caso de que o servidor admita as Extensións de CIFS de Unix, o lado do cliente (isto é, o seu lado) tenta asignarlles os UID e GID efectivos do proceso actual aos ficheiros, directorios e dispositivos novos que se creen. Se esta funcionalidade estiver desactivada, empréganse os UID e GID por omisión definidos para a compartición. Recoméndase ler a páxina do manual de mount. cifs antes de alterar esta opción.
