When I create a tool, the first field is "Unique tool name". This seems to be what becomes the tool ID (LDAP name), as seen in https://toolsadmin.wikimedia.org/tools/id/<TOOL_ID>
I seem to be able to change that "Unique tool name" when editing the toolinfo afterwards, but the tool ID remains the same, both in the URL and for usage in the terminal, e.g. with the become command. So I'm not really sure what's the point of changing that field is (and whether it's worth the potential confusion).
I'd prefer to either being able to change the tool unique name in a way that also changes its ID, or not be able to change the unique name at all (or at least have a separate "LDAP name" field in the tool creation form that has a warning saying it won't be able to be edited in the future).
