*
* @deprecated
* Azure Active Directory is now known as [Microsoft Entra ID](/getting-started/providers/microsoft-entra-id).
* Import this provider from the `providers/microsoft-entra-id` submodule instead of `providers/azure-ad`.
*
* Add Azure AD login to your page.
*
* ### Setup
*
* #### Callback URL
* ```
* https://example.com/api/auth/callback/azure-ad
* ```
*
* #### Configuration
*```ts
* import { Auth } from "@auth/core"
* import AzureAd from "@auth/core/providers/azure-ad"
*
* const request = new Request(origin)
* const response = await Auth(request, {
* providers: [
* AzureAd({
* clientId: AZURE_AD_CLIENT_ID,
* clientSecret: AZURE_AD_CLIENT_SECRET,
* }),
* ],
* })
* ```
*
* ### Resources
*
* - [AzureAd OAuth documentation](https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow/)
* - [AzureAd OAuth apps](https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app/)
*
* @example
*
* ### To allow specific Active Directory users access:
*
* - In https://portal.azure.com/ search for "Azure Active Directory", and select your organization.
* - Next, go to "App Registration" in the left menu, and create a new one.
* - Pay close attention to "Who can use this application or access this API?"
* - This allows you to scope access to specific types of user accounts
* - Only your tenant, all azure tenants, or all azure tenants and public Microsoft accounts (Skype, Xbox, Outlook.com, etc.)
* - When asked for a redirection URL, use `https://yourapplication.com/api/auth/callback/azure-ad` or for development `http://localhost:3000/api/auth/callback/azure-ad`.
* - After your App Registration is created, under "Client Credential" create your Client secret.
* - Click on "API Permissions" and click "Grant admin consent for..." to allow User.Read access to your tenant.
* - Now copy your:
* - Application (client) ID
* - Directory (tenant) ID
* - Client secret (value)
*
* In `.env.local` create the following entries:
*
* ```
* AZURE_AD_CLIENT_ID=<copy Application (client) ID here>
* AZURE_AD_CLIENT_SECRET=<copy generated client secret value here>
* AZURE_AD_TENANT_ID=<copy the tenant id here>
* ```
*
* That will default the tenant to use the `common` authorization endpoint. [For more details see here](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-v2-protocols#endpoints).
*
* :::note
* Azure AD returns the profile picture in an ArrayBuffer, instead of just a URL to the image, so our provider converts it to a base64 encoded image string and returns that instead. See: https://docs.microsoft.com/en-us/graph/api/profilephoto-get?view=graph-rest-1.0#examples. The default image size is 48x48 to avoid [running out of space](https://next-auth.js.org/faq#:~:text=What%20are%20the%20disadvantages%20of%20JSON%20Web%20Tokens%3F) in case the session is saved as a JWT.
* :::
*
* In `auth.ts` find or add the `AzureAD` entries:
*
* ```ts
* import AzureAd from "@auth/core/providers/azure-ad"
*
* ...
* providers: [
* AzureAD({
* clientId: process.env.AZURE_AD_CLIENT_ID,
* clientSecret: process.env.AZURE_AD_CLIENT_SECRET,
* tenantId: process.env.AZURE_AD_TENANT_ID,
* }),
* ]
* ...
*
* ```
*
* ### Notes
*
* By default, Auth.js assumes that the AzureAd provider is
* based on the [OAuth 2](https://www.rfc-editor.org/rfc/rfc6749.html) specification.
*
* :::tip
*
* The AzureAd provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/azure-ad.ts).
* To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/configuring-oauth-providers).
*
* :::
*
* :::info **Disclaimer**
*
* If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).
*
* Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
* the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
* we might not pursue a resolution. You can ask for more help in [Discussions](https://authjs.dev/new/github-discussions).
