I still have only the default domain so admin is in same domain as the 
project. The admin user is the main admin (it has the admin role). The 
configuration is loaded through environment variables, so no cloud.yaml 

Yes I think I have to somehow connect to the destination project but 
with the credentials of the admin (which is only member of another 
I assumed connect_as_project is the solution, but this is not working as 
expected (actually I do not understand what it is for ! or what 
configuration it expects to work (does it expect to have a member role 
in the destination project ?).

I just tried to get a token as admin and use it for authorization in the 
customers project. But no success yet.

Another approach I did not yet try is use a trust (but, if I understand 
correctly, I have to establish the trust as user of destination project 

Well and the last thing would be to add the admin user as project member 
and remove it after work is done. But I like to avoid that solution.
