Multi domain extension and Azure AD Connection

I have some trouble with Azure Ad Connection.

In my example I have 3 domains name:

These 3 domains are different and are declared as well in Azure / Office365.

When we configure first:

  1. domain.com → domain-waad OK , fine the first is configured and ready to use
  2. domain.fr → domain-waad NOK, the id become automatically the same as first and the system refuse to create it.
  3. same thing

Is there anyone who solved or skirted this issue ?

You can try to create the connection through the Management API v2 create connection endpoint as that allows you to specify the name of the connection and as such you may be able to bypass the issue caused by the auto-generation of the name when creating the connection through the Dashboard.
