This topic describes how to control access to Cloud Paralleled File System (CPFS) file systems by using an enterprise-created Lightweight Directory Access Protocol (LDAP) service.

Background information

LDAP is an application protocol that allows you to access directory services.
  • If LDAP is not integrated, CPFS file systems allow access only from root users. If other users attempt to access the file system, the error message permission denied is returned.
  • If LDAP is integrated, you must specify the required parameters that are related to an LDAP server and ensure the availability of the LDAP service.
    1. Ensure that communication is enabled between the virtual private cloud (VPC) where the LDAP server resides and the VPC where a CPFS file system resides.
    2. Ensure that the service port of the LDAP service is open. The default port number of the service port is 389.


  1. Log on to the NAS console.
  2. Choose CPFS > File System List.
  3. Find the target file system and click Manage.
  4. On the File System Details page, click Add LDAP.

    Set the URI, Bind DN, and Search Base fields.
