B2B with Microsoft Graph
<p>As you probably know, I am creating a multi-tenant azure application, which is using the B2B functionallity.</p>

<p>I am testing the B2B functionality and after some research I got a working sample.</p>

<p>Small summary: User authenticates against common authority, first token is acquired via common authority with the authorization code and from then, everytime I need a service client, I try to obtain those tokens from the 'current tenants' authority. </p>

<p>When I request 'Me', it only works against the home tenant. When I request me with a trusted tenant, I got an error that my user identifier does not exist in the directory. Probably because user does not actually exist in the trusted tenant.</p>

<p>When I request Users, it works fine. I can get both, home tenant users and trusted tenant users.</p>

<p>Is this normal behaviour? 
Is this something I need to handle programmatically or would this been solved by using the AD graph? 
(So when I know I need user info, just query the home tenant?)
Or is this a bug?</p>

<p>Any thoughts on this would be greatly appreciated!</p>
