How can I log in to Samba Domain Controller with domain account?

I have provisioned my server to domain controller using samba sudo samba-tool domain provision \ --interactive \ --use-rfc2307 \ --backend-store=mdb \ --backend-store-size=16Gb \ --function-level=2016 \ --option="ad dc functional level = 2016" I can join other machines to domain (using sssd) and log in to them using my domain accounts. But I cannot login to my domain controller with my domain administrator account. I tried sssd, but in every instruction I saw - I need to join computer to domain (but I'm already in the domain as a domain controller). Can anyone tell me if it is possible and if so, how can I do it? While I try to log in sudo login administrator@domain.name I'm getting error - user not found If I id administrator@domain.name or id administrator I also get id: «administrator@domain.name»: There is no such user
