Arvados

Related, I can't set up a user with this VM.

Here's the error.

The user setup is being forwarded to jutro. But, the VM exists on pirca, not jutro, so the setup fails with "not found" for the VM.

Findings:

1. There's a real bug setting up federated users with local VMs (#note-2)
2. If I log in as nico's user it shows 1 VM in the list on pirca. jutro is not configured with any VMs, so we expect that list to be empty. I can log in with webshell with the nico user.
3. The "mrubenfield" user is supposed to have an account on shell, but doesn't. This is why he can't login with webshell. I suspect that arvados-login-sync is skipping him because he hasn't uploaded an ssh public key. However, an ssh key is not needed to log in via webshell, so this is a bug in aravdos-login-sync.
4. The javascript timeout hack in webshell UI isn't a factor here, although it is worth fixing. Also, in the process of looking into this, I ran into an issue with rails assets which might be new in 5.2?
