OK, thanks for the response!
If there are no issues, I will use the line you suggested.

A last more theoretical question:
If I already have an installation with some BE-users, I can rename them.
This does not cause any problems with the mapping user --> author of 
content-element and what else there is.
Am I right that for lowercase/uppercase changes this is the same?
