Thanks for friendly welcome!
Since I have configured this domain as the default I should not have to enter the full user name with @domain.tld info. I have verified that I can log into this domain by turning the LDAP authentication off and I can indeed access the domain with just the user name. The answer to your question then is just the user name: kells for example.

I hope that helps!
