I have a new share setup that I would like to do some pretty simple things with. I would like to have multiple people connect to it. Everyone can read and write to it but the only creator of a given file can delete that file. Also, when a given file (say Word, Quark or Photoshop docs) is open by user1 it should be considered read-only by the other users. If user1 creates a file user2 (in the same group) should be able to edit the file as long as no one else is editing it. This seems very straight forward to me but I can't seem to have the share follow these rules. When testing I have either 2 or 3 different users connected to the share from at least 1 Windows client and 1 OS X client. OS X is going to be the main connector to this share but Windows users will be in there also. Here's the smb.conf I have: [global] idmap gid = 16777216-33554431 idmap uid = 16777216-33554431 path = /var/www/ unix password sync = yes workgroup = cmny os level = 20 auto services = advertising editorial null passwords = yes encrypt passwords = yes winbind use default domain = no security = user template shell = /bin/false lock directory = /var/lock/smb share modes = yes locking = yes [advertising] writeable = yes wide links = no path = /var/www/advertising strict locking = yes force create mode = 755 valid users = @advertising oplocks = False level2 oplocks = False Thanks!
