How to impersonate core service client when using Azure OpenIdConnect Authentication

Question

We are using SDL Tridion 9.5 and we have configured Azure OpenIdConnect Authentication using Access management for login into CME. We are working on a Custom Page using core service client but we are unable to impersonate core service client since HttpContext.Current.User.Identity.Name always return empty. What is the correct way to impersonate a core service client? Any sample code will be very helpful

Answer 1

Try getting it from the CurrentPrincipal.Identity instead:

string userName = HttpContext.Current?.User?.Identity?.Name;
if (string.IsNullOrWhiteSpace(userName))
{
    userName = System.Threading.Thread.CurrentPrincipal.Identity.Name
}

Of course that's assuming you only need the name to impersonate correctly. If you want to use external groups for security, for instance, you should probably be using the ImpersonateWithToken or ImpersonateWithClaims methods instead.
