Sort user by last name

Hello there,

can i change the sorting of user to last_name, first_name?
Actually its always first_name, last_name.

We need this specially for the overview of our vibe user when we click "Personal Workspaces" beside the "Global Workspaces".

I found an old Message, but i do not really understand it:

Any ideas ?

Vibe 3.4

Regards

Heiko
