You can only change permissions/privileges yourself in DartFS from a Windows (PC) environment. See FAQ on accessing DartFS from Windows for more help. Please contact Research Computing if you do not have access to a Windows PC, and we will be happy to help you.

Privileges you can grant:

You can grant per file/folder and per Dartmouth user/group privileges. In other words, you may grant any type of access (read/write/etc.) to any member of the Dartmouth community (with a valid NetID) or Active Directory group (previously defined group of users).

Available privileges for each file/folder are:

  • Full control — read/write/execute plus the ability to modify permissions
  • Modify — read/write/execute
  • Read & execute — but not write/modify
  • List folder contents — same as Read & execute but with a different name when applied to a folder
  • Read — but not write/modify or execute
  • Write — but not read or execute (dropbox)

Once the privileges have been granted, the grantee can access the DartFS volume using his/her own set of credentials and perform the actions you have authorized immediately.

You can edit the privileges of existing Active Directory users (i.e. have a NetId) and existing AD groups. To create new groups for your users, please e-mail us at research.computing@dartmouth.edu

 

From Windows ONLY
Changing permission in DartFS

  1. Open a Windows Explorer window
  2. Click the DartFS mounted volume found under Computer in the left-most panel. The DartFS volumes are name either using your NetID if it is a personal home directory, or named after your lab/PI name if it is a shared lab directory space.
  3. Optional: create a new folder/file
  4. Select the file/folder you would like to share/set privileges to, right-click and select Properties
  5. This window shows the current privileges setting, including user (top panel) and when you select a user, his/her permissions will be displayed in the bottom panel. For simple privileges management, like add/remove users and manage permissions, click on Edit. Note that by default, changes to the selected folder/file cascaded down recursively to all enclosed files and folders (i.e. if you make this folder readable, so will all the files and folder below the current one).

  1. For an existing user/groups, you can select that user and view their current permissions in the lower panel.
  2. To change a user/group’s permissions, select it in the upper panel, then click Edit…, the new window will allow you to Allow and Deny individual permissions
  3. To remove a user, select the user in the upper panel and click on Remove
  4. To add a new user to this directory/file, select Add…
  5. Type the name or NetId of the user or group you would like to add in the bottom object name Note that if you use the user’s name, you have to use their full name, including their middle initial. Alternatively, you can use https://dndlookup.dartmouth.edu/ to lookup the NetId of partial name matches. Existing Active Directory group names can be partial. We’ll be happy to create groups for your users.

  1. Click Check Names. If a match is found in Active Directory, the name will be capitalized and underlined. Otherwise, you will get a new window asking you to re-type the “object name” (i.e. user or group). This is why we recommend using NetId matches.
  2. Once the user was added, you can view/change the file/folder privileges in the lower panel. Again, by default, changes will be cascaded down recursively to all file/folders below the currently select folder. The Advanced button to allows you to change the cascading behavior as well as other more advanced features.
