My machine runs under Linux Mandrake Professional v9.2.

for the user "lambda" its home directory is $HOME="/home/lambda". The default permissions for the directory "lambda" are "drwx------". When I change them to "drwx--x---" with the command "chmod g+x $HOME", a few minutes later this changement is lost.

Is there a particular configuration I should do?

Thanks very much for your help.
