Specify a different backend like stable.opencast.org:

podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ghcr.io/opencast/opencast-admin-interface:pr-1368

It may take a few seconds for the interface to spin up.
It will then be available at http://127.0.0.1:3000.
For more options you can pass on to the proxy, take a look at the README.md.

Discussion at the technical meeting suggested that this reads like the user can't do anything in the ACL. I'm inclined to agree. @Arnei suggested in the technical meeting that this was possible with config changes alone though, so perhaps this becomes something where we just change hte default?

To be precise, I did not say you can configure the removal of the READ column. I said that you can configure the read/write columns to be read-only. If read-only, the respective columns are still visible, but the checkboxes are greyed out and uninteractable.

Config file: https://github.com/opencast/opencast/blob/develop/etc/listproviders/acl.default.create.properties
The READ column is read-only per default, you can see this behaviour on e.g. develop.opencast.org.
