Well, that somewhat limits the use of the recycle feature, since it 
simply doesn't work on shares accessed by multiple users.

In my opinion the behaviour should be controllable via the smb.conf file.

Anyway, thanks for your thoughts, but I chose to fix this shortcoming in 
a more clumsy way, I guess. But I might check the acl stuff sometime.

--- crontab

-* * * * *      root    /usr/bin/find /srv/samba/*/.recycle -type d 
-exec /bin/chmod g+rwx {} \;

--- contab end
