Bug #16923

workbench getting token with untrusted client
Description
Trying to share a collection as an ordinary user, but I see (on the view collection page, in wb1):
Sharing and permissions
Your API token is not authorized to manage collection sharing links.
1. Why? I see a request like this in the api server logs when loading https://workbench.tordo.arvadosapi.com/collections/tordo-4zz18-aam8gchmw53n426:
[req-7rl47pzbw1vscbqsdcj1] Error 1601328087+69320957: 403

and in the controller logs:

2. Sharing appears to be undocumented, if this is a config issue, we need to document that better

I have discovered two issues.
- In the LoginCluster configuration, a user goes to tordo, is redirected to ce8i5 for login, with return_to set to tordo workbench. This means the token is associated with the tordo workbench api_client, not ce8i5. So the default behavior of trusting a cluster's workbench doesn't apply (it knows to trust ce8i5, but not tordo).
- In arvbox, it uses the "test" login method, which uses the username/password authorization method. This method doesn't have a return_to, it provides a fake return_to called "https://none.invalid". This means when using test, pam, or LDAP authentication, it gets the "none.invalid" api_client, which is not trusted (unless explicitly configured).
For issue 1, this is actually working as intended. I think the only solution is to fix the configuration and documentation.
For issue 2, the url in createAPIClientAuthorization should be trusted by default, and tweak the bogus URL to indicate what is going on.

- In Arvados_arch.svg, the lines between 'cli tools' and 'workbench' on to the 4 boxes on the next line are confusing; cli tools can also connect to arv-ws and git, and workbench definitely talks to keep-web. Can we somehow indicate that the cli tools and workbench talk to all four boxes?
- missing 'and Workbench2' between 'Workbench1' and 'are trusted' in the comment in the config reference:
+ # When the token is returned to a client, the token itself may + # be restricted from manipulating other tokens based on whether + # the client is "trusted" or not. The local Workbench1 are + # trusted by default, but if this is a LoginCluster, you + # probably want to include the Workbench instances in the + # federation in this list.
Otherwise, LGMT, thanks!
