title: Custom Attributes/Properties in AAD .. Finding them in MS Graph
body: <p>I have large AAD Dynamic group that I need to search and query membership for (100K+ member group) and search for users by name. This group is generated based on a custom attribute on the user in AAD. </p>
  
  <p>I am trying to figure out if I can get this information out the MS Graph or if I need to move these calls to the AAD Graph ?</p>
  
  <p>I've checked the users for extensions and schema data but there doesn't seem to be anything there. </p>
  
  <p>Are custom attributes not replicated in MS Graph?</p>
  
  <p>The problem I am trying to solve is:</p>
  
  <p>I have a people picker that I want to return results that satisfy membership of a this group. The problem is MS Graph doesn't support OData queries of the members of a group on their displayName. Since the group is driving by the custom attribute I was hoping to take a short cut and include that in my query </p>
