Azure-docs: Authenticate with Azure Active Directory - Error " New-Object: Cannot find type [Microsoft.IdentityModel.Clients.ActiveDirectory.SecureClientSecret]: verify that the assembly containing this type is loaded."

[crisansou]

Hello,

I'm following the steps in the link below to perform authentication by AAD, but I received the error message "New-Object: Cannot find type [Microsoft.IdentityModel.Clients.ActiveDirectory.SecureClientSecret]: verify that the assembly containing this type is loaded".

Does anyone know how to solve this issue?

Reference: https://docs.microsoft.com/en-us/azure/cognitive-services/authentication#authenticate-with-azure-active-directory

Best regards,
Cristina

@erhopf I was able to reproduce this error when trying to get a token. Can you please review documentation? Thanks.

@crisansou, if you are using CloudShell from Azure Portal, the SecureClientSecret class is not available. You can, however, pass in the secret as a string. So you can do: $clientCredential = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.ClientCredential" -ArgumentList $app.ApplicationId,

More info on ClientCredential can be found here:
https://docs.microsoft.com/en-us/dotnet/api/microsoft.identitymodel.clients.activedirectory.clientcredential.-ctor?view=azure-dotnet-preview#Microsoft_IdentityModel_Clients_ActiveDirectory_ClientCredential__ctor_System_String_System_String_

We'll update the doc accordingly so other folks don't run into the same issue. Thanks for bringing this to our attention!

$clientCredential = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.ClientCredential" -ArgumentList $app.ApplicationId,

Ok, it worked, thank you!

Best regards,
Cristina
