Equivalence of MS Graph User Id and Azure AD Object Identifier claim?
<p>The user object returned by the <a href="https://graph.microsoft.io/en-us/docs/api-reference/v1.0/resources/user" rel="nofollow">MS Graph Users API</a> has an id field that appears to be the same as the <a href="https://azure.microsoft.com/en-us/documentation/articles/active-directory-token-and-claims/#idtokens" rel="nofollow">Azure AD ObjectIdentifier (oid</a>) claim.  Is this a documented and reliable correspondence, or if I want to obtain the object identifier, should I go through the Azure AD Graph Users API instead of the MS Graph Users API?</p>
