Hi @Sandeep Chaurasia ,
Thanks for reaching out.
I understand that you are trying to login using Angular application in Azure AD and getting the ClientConfiguration error.
This error is due to when configuration has not been correctly set in your application.
It seems in the app.module.ts application where you are setting the value of authority has not been correctly set.
If you want to authenticate users against a specific tenant, specify
authority: 'Enter_the_Cloud_Instance_Id_Here'/'Enter_the_Tenant_Info_Here',
where
Cloud_Instance_Id : https://login.microsoftonline.com
Tenant_Info : Tenant Id(GUID value) or Tenant Name(contoso.microsoft.com)
So value of authority would be
authority: https://login.microsoftonline.com/0813d94b-738a-493b-b8b4-71adaa678714
OR
authority: https://login.microsoftonline.com/contoso.onmicrosoft.com
Hope this will help to solve your issue.
Thanks,
Shweta
