Bug#255245: mldonkey-server: does run with permissions of groups that the mldonkey user is added to
Arthur Peters
Version: 2.5.21-2
Severity: normal
When the mldonkey server is started using the mldonkey_server program it switchs to
user and group mldonkey but does not show any groups to which the mldonkey user belongs.
This is a problem for me because the files I want to share are on a drive that is
only accessable by group windows and a NFS mount that is only accessable by group mp3s.
Just in case it matters, I did hack the config files by hand a bit so the debconf info in
the message may not be the current configuration.

Note that the Groups line shows nothing.
if I start mlnet using "cd ~mldonkey/; sudo -u mldonkey mlnet" I get:

Now groups includes the groups mldonkey belongs.

Well, you are right, i miss a "setgid" in the code of mldonkey_server...
I will do some tests and see if it solves your problem.
You will need to wait till the next release !
