This document forms the specifications for [Role-Based Access Control](https://en.wikipedia.org/wiki/Role-based_access_control) which was introduced as part of the **Unleash v4 release**.
2.**Project resources** - Resources which are only available under a project. Today this is only “feature toggles” (but we expect more resources to live under a project in the future). A feature toggle will belong to only one single project. In Unleash-Open source there exists only a single project, the “default” project, while Unleash Enterprise supports multiple projects.
Unleash comes with a set of built-in roles that you can use. The _global roles_ are available to all Unleash users, while the _project-based roles_ are only available to Pro and Enterprise users. The below table lists the roles, what they do, and what plans they are available in. Additionally, enterprise users can create their own [custom project roles](#custom-project-roles).
| **Admin** | Global | Users with the global admin role have superuser access to Unleash and can perform any operation within the Unleash platform. | All versions |
| **Editor** | Global | Users with the editor role have access to most features in Unleash but can not manage users and roles in the global scope. Editors will be added as project owners when creating projects and get superuser rights within the context of these projects. Users with the editor role will also get access to most permissions on the default project by default. | All versions |
| **Viewer** | Global | Users with the viewer role can read global resources in Unleash. | All versions |
| **Owner** | Project | Users with this the project owner role have full control over the project, and can add and manage other users within the project context; manage feature toggles within the project; and control advanced project features like archiving and deleting the project. | Pro and Enterprise |
| **Member** | Project | Users with the project member role are allowed to view, create, and update feature toggles within a project, but have limited permissions in regards to managing the project's user access and can not archive or delete the project. | Pro and Enterprise |
Custom project roles let you define your own roles with a specific set of project permissions down to the environment level. The roles can then be assigned to users in specific projects. All users have viewer access to all projects and resources, but must be assigned a project role to be allowed to edit a project's resources. For a step-by-step walkthrough of how to create and assign custom project roles, see [_how to create and assign custom project roles_](../how-to/how-to-create-and-assign-custom-project-roles.md).
Lets the user create feature toggles within the project and create variants for said toggle. Note that they **can not assign strategies** to toggles without having the _create activation strategy_ permission for the corresponding environment.
Lets the user update feature toggle descriptions; mark toggles as stale / not stale; add, update, and remove toggle tags; and update toggle variants within the project.
Lets the user create and edit variants within the project. (Deprecated with v4.21 in favor of environment-specific permissions for working with variants[^1].)
Lets the user approve [change requests](change-requests.md) in the environment.
- **apply a change request**
Lets the user apply change requests in the environment.
- **skip change requests**
Lets the user ignore change request requirements. This applies **only when using the API** directly; when using the admin UI, users with this permission will still need to go through the normal change request flow. You can find more details in the section on [circumventing change requests](change-requests.md#circumventing-change-requests).
User groups allow you to assign roles to a group of users within a project, rather than to a user directly. This allows you to manage your user permissions more easily when there's lots of users in the system. For a guide on how to create and manage user groups see [_how to create and manage user groups_](../how-to/how-to-create-and-manage-user-groups.md).
Groups that do not have a root role need to be assigned a role on a project to be useful. You can assign both standard roles and custom project roles to groups.
Groups that *do* have a root role can't be assigned to a project. Any user that is a member of a group with a root role will inherit that root role's permissions globally.
While a user can only have one role in a given project, a user may belong to multiple groups, and each of those groups may be given a role on a project. In the case where a given user is given permissions through more than one group, the user will inherit most permissive permissions of all their groups in that project.
User group syncing is planned to be released in Unleash 4.18 and will be available for enterprise customers.
:::
User groups also support integration with your Single Sign-On (SSO) provider. This allows you to automatically assign users to groups when they log in through SSO. Check out [_how to set up group SSO sync_](../how-to/how-to-set-up-group-sso-sync.md) for a step-by-step walkthrough.
Users that have been added to a group through your SSO provider will be automatically removed next time they log in if they've been removed from the SSO group. Users that have been manually added to the group will not be affected.
To enable group sync, you'll need to set two fields in your SSO provider configuration options:
- **enable group syncing**:
Turns on group syncing. This is disabled by default.
- **group field JSON path**
A JSON path that should point to the groups field in your token response. This should match the exact field returned by the provider. For example, if your token looks like this:
```json
{
"iss": "https://some-url.com",
"azp": "1234987819200.apps.some-url.com",
"aud": "1234987819200.apps.some-url.com",
"sub": "10769150350006150715113082367",
"at_hash": "HK6E_P6Dh8Y93mRNtsDB1Q",
"hd": "example.com",
"email": "jsmith@example.com",
"email_verified": "true",
"groups": ["test-group", "test-group-2"], //the field where groups are specified
"iat": 1353601026,
"exp": 1353604926,
"nonce": "0394852-3190485-2490358"
}
```
You need to set the "Group Field JSON path" to "groups".
Once you've enabled group syncing and set an appropriate path, you'll need to add the SSO group names to the Unleash group. This can be done by navigating to the Unleash group you want to enable sync for and adding the SSO group names to the "SSO group ID/name" property.
[^1]: The project-level permission is still required for the [**create/overwrite variants** (PUT)](/docs/reference/api/unleash/overwrite-feature-variants.api.mdx) and [**update variants** (PATCH)](/docs/reference/api/unleash/patch-feature-variants.api.mdx) API endpoints, but it is not used for anything within the admin UI. The API endpoints have been superseded by the [**create/overwrite environment variants** (PUT)](/docs/reference/api/unleash/overwrite-feature-variants-on-environments.api.mdx) and [**update environment variants** (PATCH)](/docs/reference/api/unleash/patch-environments-feature-variants.api.mdx) endpoints, respectively.
