Modifying a Dtree

Prerequisites

A namespace and a dtree have been created.

Procedure

1. Choose Resources > Resources > Dtree.
2. Select a desired account from the Account drop-down list in the upper left corner.
3. Select an owning namespace, click More on the right of a desired dtree, and select Modify.

   The Modify Dtree page is displayed.

4. Select a security style based on service requirements. Possible options are:
   • Mixed: applies to scenarios where users of CIFS clients (using the SMB protocol) and UNIX clients (using the NFS, HDFS, or DPC protocol) can access and control dtrees. In this style, CIFS permissions (NT ACLs) and UNIX permissions (UNIX mode bits, POSIX ACLs, or NFSv4 ACLs) cannot co-exist. Only the latest configured permissions on either CIFS or UNIX clients take effect.
   • Native: applies to the same scenarios as the Mixed style. The difference between the Native style and the Mixed style is that CIFS permissions (NT ACLs) and UNIX permissions (UNIX mode bits, POSIX ACLs, or NFSv4 ACLs) can co-exist and will neither affect nor synchronize with each other in Native style.
   • NTFS: applies to scenarios where Windows NT ACLs control users' permissions.
   • UNIX: applies to scenarios where UNIX mode bits, POSIX ACLs, or NFSv4 ACLs control users' permissions.
   

   In Mixed style (which supports NT ACLs), if you configure an NT ACL for a file or directory on a Windows client and switch Mixed to UNIX, the NT ACL in Mixed style will become invalid.

5. Set advanced parameters of the dtree. Click Advanced.
   Set dtree directory permissions and select permission types as required. Table 1 describes related parameters.

   Table 1 Dtree directory permissions

   Parameter	Description
   User	Indicates permissions of the owner. The permission types include Read, Write, and Execute.
   User Group	Indicates permissions of other users in the group to which the current user belongs. The permission types include Read, Write, and Execute.
   Others	Indicates permissions of any user. The permission types include Read, Write, and Execute.

   

   • If dtree directory permissions are modified, the configured ACL policy of the current dtree will become invalid.
   • Dtree directory permissions cannot be modified in NTFS security style.

6. Click OK.
