ClaimsPrincipal cp = ClaimsPrincipal.Current;
ClaimsIdentity ci = cp.Identity as ClaimsIdentity;
BootstrapContext bc = ci.BootstrapContext as BootstrapContext;
SecurityToken securityToken = bc.SecurityToken;

You also need to set the saveBootstrapContext attribute in your config file:

<system.identityModel>
    <identityConfiguration saveBootstrapContext="true">
    ...
</system.identityModel>

Thanks, but these don't address my question. I am trying to use a simple Java program to get authorization

token from Azure AD in order to use Power BI RESt api. I am having trouble  as I described above. Thanks again.

    Have you looked at the body of the 400 response to see if there's any additional information?

      Thanks for responding.

      Somehow the http 400 throws a java IOException. In the exception code I tried reading getErrorStream() from the

      HttpURLConnection ('conn' in my code above) but nothing meaningful came down. I know there is supposed to be a json

      returned w/ the 400. getInputStream() didn't return anything either. Do you know how to get to it in java?

        I'm sorry, I'm not familiar with the Java HTTP libraries.
