CLI Command to get User-ID and Space-ID

[mmattel]

While documenting search how to reindex a space (cli command), I came across the point that we need as parameters a user-ID and space-ID as parameters. But getting these ID's is, except when using a browser console and then only for non-home spaces the admin has access to, currently not possible.

Here is a proposal to get around this situation:
We need to implement a CLI command (similar to nslookup) that resolves:

• a user name to its ID and vice versa
• a space name to its ID and vice versa
• prints the home-space ID of a given user-ID

Maybe to add this to the Infinite Scale Team Board?

With #5617, we add the ability to assign default role based quotas via yaml config. This config needs a role defined by its ID. Currently there is no way for an admin to get the role ID.

This is not so easy. In ocis there is no real command line. If we use the command line, we need to authenticate because the command line needs to call other services.

However we make it, take this issue as collector where particular info currently not available is further needed either for configuration or for existing (or upcoming) command lines calls.

we can create a service account for the cli ... once we get #5550 fixed ... 😞
