[keycloak-user] Realm resolution by username

[Ian Duffy]

Hi all,

I'm using keycloak in a multi-tenant scenario where each tenant is a realm
and the clients are duplicated across them.

The username for each user is an email address of username at tenant.tld

Is there any way to use the @tenant.tld part of the email address as a
realm resolver and have all users access the system
via the same login page?

Thanks,
Ian.
