Cross-Domain Identity, Supported?

[jordanabakerafs]

Good Afternoon XRM Community,

We have a use case in our solution where we are B2B inviting users from a different tenant. These users have admin level access in application but are unable to see our crm instances in the XRM toolbox connections after authenticating. No instances are shown, which is correct for their home tenant, as it does not have any.

Does XRMToolbox support logins for users whose identities are cross-domain or cross-tenant? If so - is there documentation on how these users might log in? We were unable to find any pointed info.

Thanks!
