After an upgrade to Ubuntu Lucid Lynx, all Samba shares were missing symlinks, esp. symlinks to directories outside the share.

To enable these again, add the following lines into the [global] section of your /etc/samba/smb.conf:

{% highlight ini %}

follow symlinks = yes wide links = yes unix extensions = no

{% endhighlight %}

Then restart smbd and you should see the symlinks again.
