Manage PTS Groups


Note: This utility is used to create and manage personally defined pts groups. Groups created by the system administrators to manage group and department AFS directories cannot be managed through this utility.

A pts group (sometimes referred to as a protection group) is a list of specific users that you can place on access control lists (ACLs). It provides a way to give permissions to a set of directories to many people.

You own all the files and subdirectories in your account, and you can determine who gets access to your files. You can create your own groups of people, and then give them permissions to your files. When you create a pts group, you automatically become its owner. Only the owner of a group can add members, remove members, or delete the group entirely.

In AFS, permissions are set by directory, not by file. Every file in a directory has the same permission. New sub-directories inherit the permissions of their parent directories. An ACL can have up to twenty entries, but a pts group, regardless of the number of people in it, only counts as one entry. There is no restriction on the number of members in a pts group.

See Setting Permissions with Windows for more information.

Add a PTS group to an AFS access control list (ACL)

  1. In Stanford OpenAFS, mount the volume that contains the directory for which you want to add a pts group to the access control list. The volume will open in Windows Explorer. (If the volume is already mounted, navigate to the directory.)
  2. Right-click the directory and select AFS > Access Control Lists.

    access control list menu
  3. When the Set AFS ACL window is displayed, click Add.

  4. Check the boxes for the permissions you want to grant to the members of the pts group. In the Name field, enter the name of the pts group, which must start with your SUNet ID and a colon.

    Note: See More about Permissions for a description of each permission.
