What if:
- User1 has TenantA as her default tenant Should the service authenticate the user against TenantA? And if so, why? What does the 'default tenant' grant User1 on TenantA? It's some nebulous, implied role… From: "Rouault, Jason (Cloud Services)" <jason.roua...@hp.com<mailto:jason.roua...@hp.com>> Date: Wed, 13 Jul 2011 13:18:44 +0000 To: Ziad Sawalha <ziad.sawa...@rackspace.com<mailto:ziad.sawa...@rackspace.com>>, Yuriy Taraday <yorik....@gmail.com<mailto:yorik....@gmail.com>>, "openstack@lists.launchpad.net<mailto:openstack@lists.launchpad.net>" <openstack@lists.launchpad.net<mailto:openstack@lists.launchpad.net>> Subject: RE: [Openstack] Keystone tenants vs. Nova projects If a user is bound to their default tenant, why wouldn’t any role assignments for that user in their default tenant apply? User1 authenticates specifying TenantB, this binds User1 into the context of TenantB. In subsequent web service requests using the token received after authentication, the Auth component filter would decorate the headers with RoleY. If User1 authenticates specifying TenantA, or specifying no Tenant, this binds User1 into the context of TenantA. The headers would then be decorated with RoleX.

You can provide access to multiple tenants using a role assignment (assigning a user a role on a specific tenant effectively binds them to that tenant). However, this raises the issue of what the 'implied' role of a user is when they are bound to their default tenant. So we're considering how to alter the model to clean that up. No great solution yet. Any suggestions are welcome….

It conflicts with the fact that in Nova user can have access to several projects. Which way will it be?
