# Authentication provider compatibility

Octopus ships with a number of authentication providers. The support for these providers differ between Octopus Server, [Octopus Cloud](/docs/octopus-cloud/) and the [Octopus Linux Container](/docs/installation/octopus-server-linux-container). Some authentication providers only work with Octopus Server, whilst others only work with Octopus Cloud. This page describes the compatibility of these providers in Octopus.

:::div{.hint}
Most of the authentication providers listed here are available in modern versions of Octopus. However, some are shipped with Octopus from a specific version. Where this is the case, the version will be noted alongside the provider.

## External groups and roles support {#external-groups-and-roles}

Octopus allows [external groups and roles](/docs/security/users-and-teams/external-groups-and-roles) to be added as members of Teams in Octopus. The following table shows which authentication providers support this in Octopus Server, Octopus Cloud, and the Octopus Linux Container:

|                                              |              Octopus Server              |              Octopus Cloud               |         Octopus Linux Container          |
|----------------------------------------------|:----------------------------------------:|:----------------------------------------:|:----------------------------------------:|

<span id="table-note-2">**\***</span> For Microsoft Entra ID users and groups, these must also be mapped in the Entra ID App Registration. Please read the [Mapping Entra ID users into Octopus teams](/docs/security/authentication/azure-ad-authentication/#mapping-aad-users-into-octopus-teams-optional) section for more details. For Octopus Cloud, external groups and roles cannot be configured for Azure AD when using [Octopus ID](/docs/security/authentication/octopusid-authentication).

<span id="table-note-3">**†**</span> For Okta groups to flow through to Octopus, you'll need to change the _Groups claim_ fields. Please read the [Okta group integration](/docs/security/authentication/okta-authentication/#okta-groups) section for more details.

:::div{.hint}
[Octopus ID](/docs/security/authentication/octopusid-authentication/) does not currently support configuring [external groups and roles](/docs/security/users-and-teams/external-groups-and-roles).
