I followed the instructions for setting up Windows10 to use FreeIPA for authentication

https://www.freeipa.org/page/Windows_authentication_against_FreeIPA

After following the instruction, the default domain displayed on windows 10 login screen is EXAMPLE and EXAMPLE.COM. I am able to login by entering EXAMPLE.COM\user as the username. But when I enter the username without the leading domain name, login fails with 'Client not found in Kerberos database' error.

Is it possible to change the default domain in windows login screen to EXAMPLE.COM from EXAMPLE?

Thanks,
