Expected results:

Either test1 should be deleted, or there should be an error why it's
not deleted. I'm not sure if directories with items in them can even
be deleted with smbclient, but nevertheless there should be an error.
Even when enabling debug with -d 10, there is no error.

smb: \noperms\> rmdir test1
dos_clean_name [\noperms\test1]
unix_clean_name [\noperms\test1]
smb: \noperms\>

For what it's worth, when I try to remove this same directory on macOS
10.13 or Windows 10, it is deleted. Whereas with GNOME Nautilus, it is
likewise not deleted (same results as smbclient, it's not deleted and
there's no error.) So I'm not sure yet if there is a wider bug here
that affects libsmbclient or what. I've filed a bug about that here:

https://bugzilla.gnome.org/show_bug.cgi?id=792147

That bug contains attachments for the server and client smb.conf and
some other stuff.
