Azure AD: User Identities

whgibbo 0 Reputation points

I have an app that needs to work with OnPremise AD and Azure AD.. Currently we are obtaining the logged in user via a windows API. Same value can be seen when using command line tools:

  • whoami
  • dsregcmd /status

Now when the user is a pure Azure AD user (I.E. machine is not joined to onpremise AD and user only exists in Azure AD) we see the following:

  • whoami - azuread**surnameforename or azuread**forenamesurname
  • dsregcmd / status (Executing Account Name) - azuread**surnameforename or azuread**forenamesurname and the usersemailaddress.

So here is the questions/issues:

  1. I've checked and output of graph requests and can't see an attribute for this... Am I missing something?
  2. The value here seems to match the displayname with any non samaccountname characters removed. However the display name is not unique. When you have 2 users with the same value you see the second user has the following suffixed added _x1as1of

Any thoughts on this, as it seems a little odd

    Hi @whgibbo , for Microsoft graph,

    you can use the GET /users/{id | userPrincipalName} endpoint to get information about users in your AD tenant. And use $select to get the other properties and relationships for the user object. Hope this help you. Best Wishes.

    Did some digging seems that Microsoft opted to used the displayname and has been like that for 12 years!

    So can't see it changing.. :(
