Log in to custom domain with having to create a new user profile. RRS feed

  • Question

  • Hola, everyone.

    Currently, using default "onmicrosoft.com" domain in our Azure AD. Recently, we created a new custom domain. My question is:

    - Do I need to disconnect each laptop connected to "onmicrosoft.com" and join them to the new custom domain? 

    - If no need to disconnect, will it be possible to log in to the custom domain without havin to create a new user profile? 

    It's more of just the custom domain not detecting a new log in and just using the cache of "onmicrosoft.com" or just creating an alias? Is this doable?

  • Hello Mister_Jay

    As per the infromation provided by you , I am assuming that your users client machines run windows 10 . What exactly do you logon to the computer right now with ? Is it something like AzureAD\user@<tenant>.onmicrosoft.com ? You would need to logon to the User's UPN value which would be user@<tenant>.onmicrosoft.com . The value of the user will not change. I am not sure what you exactly mean when you say that "will it be possible to login to the custom domain?" becasue for that , you would need to change the existing user's UPN value in the cloud from user@<tenant..onmicrosoft.com to user@<domain>.TLD . And then only you can use the new UPN value as user's username which can be used to logon. In this case , It will create a new User profile in all probability. 

    Also as far as I think , you do not need to rejoin the laptop to the domain as you are in the same tenant. The machine will still get a PRT (primary refresh token in case of win10) from the cloud and continue to work . 

    Hope this clarifies your queries. Please let us know in case you have any further queries. In case the details help you , please do mark this post as an answer so that other users having similar queries can benefit from the same. 

    Thank you.
