The symlink does point outside the exported tree. The export is /srv/www and the symlink is /srv/www/homes which points to /home Anyway, I tried setting this in the global section: unix extensions = no follow symlinks = yes as well as follow symlinks = yes in the share config. I still can't access the symlinked directory from /srv/www so the question is if there's a bug in openSUSE's implementation of the samba server. Read Adam's email again.
You need wide links = yes as well. Joachim -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Joachim Schrod Email: jschrod@acm.org Roedermark, Germany -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Wide links = Yes was the default until about this time last year. There there was a huge hubbub on the net about a claimed zero-day exploit of /etc/passwd which Samba.org mentioned here: http://www.samba.org/samba/news/symlink_attack.html Samba changed the default, but I still fail to see how simple read access to /etc/passwd is a big deal. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've tried that, it doesn't doa ny good. I've tested using it both in the global section (recognized) and in the share section (error, should be used in the global section). It seems like I'm in a deadlock, perhaps I should post a bugzilla report? It doesn't work in any version after 11.1, the latest I've tried is 12.1 MS2.
