Hi @billy2 Thank you for reaching out to us! After reading through your use-case, I did some digging around and it appears that “tenant\_domain” is merged with the “domain\_aliases” array, and the resultant array is what is used for Home Realm Discovery. " tenant\_domain " seems to be more of a legacy field that only accepts a String and is limited to one entry. Doing some testing with the [Management API](https://auth0.com/docs/api/management/v2/connections/get-connections-by-id), “tenant\_domain” is not automatically created when setting “domain\_aliases”. As you have mentioned, using only `tenant_domain` seems to be working correctly, but it will indeed not list the configured “tenant\_domain” in the connection’s “Identity Provider Domains” box. My recommendation is to just use the “[domain\_aliases](https://registry.terraform.io/providers/auth0/auth0/latest/docs/resources/connection#domain_aliases-1)” array to record your customer’s email domains that should be routed to the connection in question, and the “tenant\_domain” attribute can be omitted from the configuration. As the connection is working correctly for you, this is solely a UI issue ( which can create confusion). This was similarly mentioned in the following [Community Post](https://community.auth0.com/t/how-to-add-identity-provider-domains-in-saml-connection-using-terraform/109783) as well, where `domain_aliases` was used in the same fashion instead of `tenant_domain`. I would also recommend to provide this feedback to our Product team via the [Feedback](https://auth0.com/feedback) page. Others can vote on the suggestion and this can lead to UI improvements and fixed to avoid such confusions in the future. Hope this helped!
