Hi Jeremy,
Thanks for your response, but it doesn't work either with exactly the same symptoms:

[2007/04/24 09:52:43, 3] smbd/process.c:switch_message(926)
  switch message SMBrmdir (pid 19730) conn 0x80414a30

  change_to_user: Skipping user change - already user
[2007/04/24 09:52:43, 5] smbd/filename.c:unix_convert(147)

[2007/04/24 09:52:43, 10] smbd/statcache.c:stat_cache_lookup(248)
  stat_cache_lookup: lookup succeeded for name [MY_TEST_LINK] -> [my_test_link]
[2007/04/24 09:52:43, 3] smbd/reply.c:rmdir_internals(3947)
  rmdir_internals: couldn't remove directory my_test_link : Not a directory
[2007/04/24 09:52:43, 3] smbd/error.c:error_packet_set(106)
  error packet at smbd/reply.c(4001) cmd=1 (SMBrmdir) NT_STATUS_NOT_A_DIRECTORY

Test setup is my_test_link -> my_test. There is a number of files/dirs in my_test. They are deleted, but not my_test_link. At the same time I can delete my_test without any problems. 

If you wish I can provide you with additional info like strace output or something.

Regards,
Alexander
