[Samba] guest share writable but unable to delete

[Peter Baranyi]

hi, I set up a share with writeable = yes, guest only = yes, guest ok
= yes, so I can connect without password and create files in the name
of the specified guest account unix user .  but I am unable to delete
the created file!
	     
I can only delete the file if the parent directory has other
permissions set to +w

it seems that samba is creating the file using the guest account user,
but deletion is done with user nobody!  how can this be?  did I do a
configuration error?
