Username passthrough to docker backend

[bmeekhof]

Hi, I'm running containerssh with the docker backend, OIDC device auth, and an authz webhook server. I'm able to authenticate and get successful request/response from my webhook server but regardless of what I set authenticatedUsername to the backend always spins up containers as user root (my containerssh server is running is root). Is there a way to pass the authenticated username through to the container the docker backend spins up?

I realize there is a static 'user:' param that can be used but this isn't quite what I'm looking for. If I login as a username, I want my name in the container to be that username.

The username you see on linux is just an alias for an id (usually stored in /etc/passwd, or fetched through LDAP). You cannot use a user/username unless the user exists there. So if you want to do that you'll either need to declare all the users in /etc/passwd that are going to log in, or use LDAP with a service like sssd to fetch the user information. Then you can set the user the same way from the configuration server.
