Configuration

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.
• 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.

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 in case the session is saved as a JWT.

In pages/api/auth/[...nextauth].js find or add the AzureAD entries:

import AzureADProvider from "next-auth/providers/azure-ad";

...
providers: [
  AzureADProvider({
    clientId: process.env.AZURE_AD_CLIENT_ID,
    clientSecret: process.env.AZURE_AD_CLIENT_SECRET,
    tenantId: process.env.AZURE_AD_TENANT_ID,
  }),
]
...
