Read 'Attribute & Claims' from SAML Entra application configuration using PowerShell


I want to read 'Attribute & Claims' from SAML enterprise application configuration using PowerShell.

I have found the Graph command Get-MgBetaServicePrincipalClaimMappingPolicy: https://learn.microsoft.com/en-us/graph/api/serviceprincipal-list-claimsmappingpolicies?view=graph-rest-beta&tabs=powershell but it always return empty value, even if I can see that attributes are configured in Azure Portal. Portal

I am using graph scope: Application.Read.All and Policy.Read.All

Any idea how I can read this configuration?

Regards


Solution

  • You can now use the beta version of the MS Graph API and push a claims policy to the application. This will overwrite the claims in the Application's UI above, but it also allows the claims to be queried & updated through both the API and UI afterwards.

    https://learn.microsoft.com/en-us/entra/identity-platform/reference-claims-customization

    enter image description here

    Once you do so, this is what the output of a GET command is.

    {
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#servicePrincipals('service_principal_id')/claimsPolicy/$entity",
    "@microsoft.graph.tips": "Use $select to choose only the properties your app needs, as this can lead to performance improvements. For example: GET servicePrincipals('<guid>')/claimsPolicy?$select=audienceOverride,claims",
