What Are Permission Management Modes Provided for the File System Shared by the Clustered NAS Storage System?
The clustered NAS storage system supports the CIFS share, NFS share, FTP share, and HTTP share. For the CIFS share, the authentication modes include local authentication and domain authentication. The locally authenticated permissions are managed based on local groups. The domain authentication permissions are managed based on files which are configured by the AD domain administrator after the clustered NAS storage system is added to the AD domain. For the NFS share, the permissions on the file system are managed and controlled by providing a specific client or network group in NFS mode. Sharing the file system to the network group requires that the clustered NAS storage system be added to the LDAP domain or NIS domain. Therefore, you can manage the permission on the file system by configuring and managing the network information (user information or group information) of the LDAP domain server or NIS domain server. For the FTP share, you can assign different permissions to users for one directory or folder. You can set the maximum number of access threads of an IP address and setting the ports of the FTP server. This function enables users to flexibly configure the FTP service and maintain the FTP server. For the HTTP share, users are allowed to access the file system through HTTP. HTTP is a protocol used for servers to transfer hypertext to local browsers.
