Change permission levels


As roles and responsibilities change in your team, you might need to change the permission levels for individual team members, or for the team as a whole. Permissions are different than access levels. If you're just trying to give someone access to a product backlog or the provide feedback features, you'll want to change access levels, not permissions.

There's a lot to learn about permissions, but here's some things you should understand before you change any permissions in TFS:

  • Permissions allow or deny users the ability to perform specific tasks, and are usually inherited from group membership.

  • A permission that is not set implicitly denies users the ability to perform tasks that require that permission, but allows membership in a group that does have that permission set to take precedence, also known as inherited allow and inherited deny.

  • For almost all permissions, deny trumps allow, so if a user belongs to two groups, and one of them has a specific permission set to deny, that user will not be able to perform tasks that require that permission even if they belong to a group that has that permission set to allow.

  • Changing a permission for a group changes that permission for all users who are granted that permission through their membership in that group. In other words, depending on the size of the group, you might affect the ability of hundreds of users to do their jobs by changing just one permission. So make sure you understand the impact before you make a change. Two useful tricks for understanding the effects of change: The member of tab shows the groups that an individual user or group belongs to. You can also hover over an inherited permission, and a why? icon will appear. If you choose it, a dialog box will open with more information.

That's the basics.

Now let's get started changing permissions!

The rest of the procedures in this topic require you to be a project administrator, so first double-check that you are one.

  1. Open the administrative context for your team project. Settings icon

  2. In the security tab, under users, find your own name, and look at what groups you belong to and what permissions you have.

  3. If you aren't a project administrator, you need to be. Find someone who is, and have them add you:

    You can add more than one person at a time

When a team is created, the team group is added to the Contributors group for the team project, by default. So when you add a team member, that person is also added to the Contributors group by virtue of being a member of your team. If you want team members to have different permissions, you can change the permissions for the team group. This will not change the permissions for all users of the Contributors group, but just for members of that one team.

  1. Now that you're a project administrator, go to the security tab and choose the team group whose permissions you want to change.

    The screen shows permissions granted to the team
  2. Look at the permissions that the team group has by default. You'll see that a lot of them are set to inherited allow. That's because the team group is a member of the Contributors group for the team project. To give the team group a different set of permissions than that group, choose a permission from the list and change it. For example, let's say you don't want anyone on this team to have permission to delete test runs, so change that permission from inherited allow to deny.

    The team inherits permissions from Contributors

    Tip: It's a good idea to test changes in permissions immediately after you make them.

  3. Teams can also have specific permissions for the areas and iterations that they work in. Because areas and iterations affect an entire project, and not just the individual team, the default value is not set. Usually, project administrators don’t change this, but you can set them specifically. To do this, you must first navigate to areas or iterations and open the security context.

    Each iteration has its own security
  4. Add the team group to the list of groups if it doesn't already appear there (by default, it won't until someone adds it), and then set the permissions for the group.

    Changes to iterations affect the whole team

Alternatively, you might want to manage the permissions of individual team members. This takes a little more work and is more time-consuming to manage, but allows you a finer degree of control over who can do what.

  1. Go to the security tab and change views so that you're looking at users, not groups.

  2. Choose the user whose permissions you want to change and change it. For example, let's say you want a particular user to have permission to delete the team project. Set that permission to allow.

    Explicit permissions override inherited ones

    That allow will override the not set that exists for the team.
