When a domain user maps a network drive to an SMB share on a Qumulo cluster, her account might not have the permissions required for adding users or groups or changing permissions on that share, which causes Windows to display a message similar to the following:

An error occurred while applying security information to:
Z:\
Failed to enumerate objects in the container. Access is denied.
This section explains how to resolve access issues when mapping a network drive to an SMB share on a Qumulo cluster by disconnecting existing shares, mapping a new network drive, and testing adding users or groups to the SMB share on clients running Windows 7 (or higher).

Step 1: Disconnecting Existing Shares

By default, a Qumulo cluster has a local administrative account that you can use to set permissions on / (the root directory) and its subdirectories.

To be able to log in to the cluster with the local administrative account, take one of the following steps:

  • In File Explorer (or Windows Explorer), right-click the network drive and then click Disconnect.

  • At the command prompt, close all shares currently mapped on the client by running the following command:

    net use * /delete

Step 2: Mapping a Network Drive to an SMB Share on a Qumulo Cluster

  1. After you disconnect all shares, in File Explorer (or Windows Explorer), right-click This PC (or Computer) and then click Map network drive.

  2. In the Map Network Drive dialog box, take the following steps:

    1. For Drive, select a drive letter.

    2. For Folder, enter a path to the SMB share.

    3. Click Connect using different credentials.

  3. In the Windows Security: Enter network credentials dialog box, take the following steps:

    1. For the username, enter qumulo\admin.

    2. For the password, enter your Qumulo cluster password.

    3. Click OK.

Step 3: Testing Adding Users or Groups to the SMB Share

  1. Right-click a file and then click Properties.

  2. In the <file name> Properties dialog box, click Security and then check that you are logged in to the Qumulo cluster with the local administrative account.

  3. To add a domain user or group, under Group or user names, click your username and then click Edit.

  4. In the Permissions for <username> dialog box, click Add.

  5. In the Select Users, Computers, Service Accounts, or Groups dialog box, enter a domain user or group, click Check Names, and then click OK.

  6. In the Permissions for <username> dialog box, click Apply.

  7. In the <file name> Properties dialog box, click OK.
