I believe this is a different problem. There is just no conversion of group
and user names to the desired character set.
With the patch below applied I get:
hasch at tower:~> getent group
Now the correct usernames and groups are shown. I only added a few
conversions, the correct approach would be to check all
unistr2_to_ascii calls and add dos_to_unix where neccessary.
I will generate a complete patch if the Samba team thinks it's worth
considering and I am not completely on the wrong track :-)
