Thanks for the question. Yes, it is currently possible to connect your data source in Cognitive Search using a service principal. You can use Azure Active Directory (Azure AD) authentication with Cognitive Search to create and use service principals for authenticating data sources.
To create a service principal, you will need to follow these high-level steps:
- Register an application in Azure AD
- Create a client secret for the application
- Grant the necessary permissions to the application in Azure AD
- Use the application's credentials to connect to the data source in Cognitive Search
Here are some more detailed steps to follow:
- Register an application in Azure AD: a. Go to the Azure portal and open the Azure AD tenant where you want to register the application. b. Select "App registrations" and then click "New registration". c. Provide a name for the application and select the appropriate options for the supported account types and redirect URIs. d. After the registration is complete, note down the application ID.
- Create a client secret for the application: a. In the application overview page, click "Certificates & secrets" and then click "New client secret". b. Enter a description for the secret, select an expiration time, and click "Add". c. Note down the value of the client secret.
- Grant the necessary permissions to the application in Azure AD: a. In the application overview page, click "API permissions" and then click "Add a permission". b. Select the appropriate APIs and permissions for your data source. c. After selecting the APIs and permissions, click "Grant admin consent for {your tenant name}".
- Use the application's credentials to connect to the data source in Cognitive Search: a. In the Cognitive Search portal, go to your data source and click "Connect". b. Select "Azure AD" as the authentication type and enter the application ID, client secret, and tenant ID. c. Test the connection to ensure that it works properly.
