The permissions for the upload folder are drwx-wx--- and the owner is
Bob group is ftpuploadgroup

Alice is member of that group, but should only drop files in.

The files are ownd by Alice, and I'm bit iritated, taht Bob can rename
tham ... as Bob only has read permision (from the group)

The files in a subfolder have the same permissions and Bob cant change

    Thanks for your feedback . /G
