[Samba] File browser doesn't remember last directory over Dfs

[Simon Walton]

Hi,

   I have encountered some strange behaviour after upgrading to
3.0.12 on FreeBSD 4.10 file servers. 

   Normally when users on windows apps use the file browser to select
a file it remembers the selected directory between invocations, so
that, for example, they can easily read in multiple files from
the same directory, or if they click on Save As... it takes
them to the directory where they last saved.

   However if the path follows a Dfs link on the samba server this
does not happen, and the file browser always opens up in some
default location (under Docs and Settings locally). This was
observed on Win 2k SP4 and Win XP SP2. Downgrading to 3.0.7
(on the server with the Dfs tree) fixed the problem. Upgrading
to 3.0.13 did not fix it.

   I turned up logging on the server with the problem and it looks
like when you bring up the file browser it tries to stat the location
but fails like so:

[2005/04/05 14:29:30, 3] smbd/trans2.c:call_trans2findfirst(1351)
  call_trans2findfirst: dirtype = 22, maxentries = 1366, close_after_first=1, close_if_end = 2 requires_resume_key = 4 level = 0x104, max_data_bytes = 16384
[2005/04/05 14:29:30, 3] smbd/msdfs.c:dfs_redirect(391)
  dfs_redirect: Redirecting m-6/v/MWD/vid_rez_Archives
[2005/04/05 14:29:30, 3] smbd/error.c:error_packet(105)
  error string = No such file or directory
[2005/04/05 14:29:30, 3] smbd/error.c:error_packet(129)
  error packet at smbd/trans2.c(1381) cmd=50 (SMBtrans2) NT_STATUS_PATH_NOT_COVERED

In this example /v/MWD/vid_rez_Archives is a Dfs link.

   I saw in the archives mention of a problem executing files over Dfs links;
I don't know if this is related.
