samba-gpupdate -d3 should print log messages issued with log.info(). However this doesn't work. I have the following patch:

When running gpupdate I can see

XXXXXX log_level= 3                                                                                                                                                                  
XXXXXX setting log level to logging.INFO
XXXXXX effective log level:  30

However I don't get the line with "What a wurst!". I have no idea what's wrong here.
