Allow multi domains on workspace

[ruipoliveira]

I have an issue on the communication with fief server. Considering two containers:

• container 1: fief server
• container 2: my container that comunicate with the fief admin server api

On container 2, when trying the request to fief server, receive the error _CANT_DETERMINE_VALIDWORKSPACE.

curl --location --request GET 'http://fief-server:8000/admin/api/permissions?query=test:create' 
--header 'Authorization: Bearer **key**'
{"detail":"CANT_DETERMINE_VALID_WORKSPACE"}

The small PR solve my problem, and allow multi domains for one workspace.

Hi @ruipoliveira 👋

I understand what you're trying to do, but unfortunately, I'm not willing to merge this into the main branch, as it would have lot of consequences and security issues.

I suggest you open a question in the Discussions so we can review together what is your config now and what you're trying to do.
