# SAML 2.0

SAML-based single sign-on (SSO) gives users access to their Federated Directory through an identity provider (IDP) of your choice.

## Authentication

If your identity provider of choice does not have a ready made integration with us, you have the option to use a custom SAML connection.

Enabling this, is as easy as selecting `SAML 2.0` from the authentication settings on a directory.

| Input                    | Description                                                                                                                         |
| :------------------------ | :------------------------------------------------------------------------------------------------------------------------------------ |
| Login page URL           | Required. SAML request will be send to this URL of your identity provider                                                           |
| Verification certificate | Required. The SAML response must be signed, and you will need to paste a valid X.509 formatted certificate to verify your identity. |
| Logout page URL          | Optional. Your users will be redirected to this URL after they log out.                                                             |

During the authentication process we map the users id (`nameID`) with the `userName` of this user within our directory. We only allow access to those users we know.
Make sure the users ID is immutable and unique.

Your IDP must ensure a user is both authenticated and authorized before sending an assertion. If a user isn't authorized, assertions should not be sent. We recommend your IDP redirect a user to an HTTP 403 page or something similar.

A SAML integration delivers SSO for your users. It can be combined with any of the user management options we [offer](./directories#automatically).
Just make sure the userName of the user is filled properly.
