[Samba] Symlinks deletion behaviour

Hi List, hi Samba-team,

Recently I've faced some problem with directories deletion trough Samba and trying to clarify the root cause. The following happens:
1. There is a directory my_dir and symlink to it my_dir_link

drwxrwsr-x  48 myuser mygroup 20480 Mar 18 21:53 .
drwxr-xr-x  33 root     root         0 Feb 28 17:37 ..
drwxr-sr-x   2 myuser mygroup  4096 Mar 18 21:47 my_dir
lrwxrwxrwx   1 myuser mygroup    57 Mar 18 21:53 my_dir_link -> /test/my_dir/

2. When I try to delete my_dir_link via Windows Explorer (under myuser who is a memeber of mygroup) I get "Cannot remove folder my_dir_link: The directory name is invalid". At the same time all files from my_dir_link(=my_dir) being deleted ok. My_dir can be deleted without any problem

In the log I see the following:
[2007/03/18 23:50:42, 5] smbd/filename.c:unix_convert(108)
  unix_convert called on file "test/my_dir_link"
[2007/03/18 23:50:42, 3] smbd/reply.c:rmdir_internals(3923)
  rmdir_internals: couldn't remove directory test/my_dir_link : Not a directory
[2007/03/18 23:50:42, 3] smbd/error.c:unix_error_packet(91)
  unix_error_packet: error string = Not a directory
[2007/03/18 23:50:42, 3] smbd/error.c:error_packet(147)
  error packet at smbd/trans2.c(2592) cmd=1 (SMBrmdir) NT_STATUS_NOT_A_DIRECTORY

Share is defined as follows:
        path = /share
        force user = myuser
        force group = mygroup
        read only = No
        strict allocate = Yes
        printable = no
        follow symlinks = Yes
        wide links = Yes

So, is it an expected behaviour, bug or something? Any clue is highly appreciated. I'm using Samba 3.0.20b from SLES9, but testing showed the same behaviour on 3.0.22 as well.
