SAML 2.0 with Azure Entra ID
----------------------------

**This plugin is available only in EE Edition.**

|RCE| supports SAML 2.0 Authentication with Azure Entra ID provider. This allows
users to log-in to RhodeCode via SSO mechanism of external identity provider
such as Azure AD. The login can be triggered either by the external IDP, or internally
by clicking specific authentication button on the log-in page.


Configuration steps

1. From the |RCE| interface, select
   :menuselection:`Admin --> Authentication`
2. Activate the `Azure Entra ID` plugin and select :guilabel:`Save`
3. Go to newly available menu option called `Azure Entra ID` on the left side.
4. Check the `enabled` check box in the plugin configuration section,
   and fill in the required SAML information and :guilabel:`Save`, for more details,
