Adding Custom domain names in Azure Active Directory

Hi Friends,

In this section, we are going to delve further in Azure AD and see how to add custom domains in it.

  • In the previous example, you have seen that we created one user with the name Johnny Page. But, it got created on domain rahulaz.onmicrosoft.com, which many a time isn’t preferred in organizations.

  • Let’s say, I have any user on company domain or on let’s say gmail account and I want to use Single Sign On (SSO) feature. In that case, above example won’t work. We need some way to add custom domain here.

  • We can certainly do it from Active Directory as shown below.

  • Upon successful verification, it will appear like this:

  • At this instant, when I see on custom domain names page, I can see like

  • Now, If I go and create a user with this domain, then it will allow me since its a valid domain now.

  • Hence, now I have these many users.
