Hi,

we do have the following problem:

when a directory has the delete_child permission, after changing mode bits the delete_child right has gone!

See this dialog:

We already tried also aclmode=discard and aclinherit=restricted, but to no help.

the missing delete_child permission creates trouble for our windows users, they can not move or delete files.

On a nexenta box this does not happen!
