I think, there should not be such thing as default tenant.<div>If user does not specify tenant in authentication data, ones token should not be bound to any tenant, and user should have access to resources based on global role assignments.</div>
<div>If user specify tenant, one should be either explicitly bound to tenant (probably through UserRoleAssignment model, but it is not the best way) or in some global role. Then one will have access to resources based on global role assignments and tenant role assignments.</div>
<div>I'm not sure whether users should be added to a tenant and then to roles in this tenant or we should remove totally direct link between user and tenant, so that user is in tenant if and only if one is in any role in this tenant.<br clear="all">
