[Samba] OT: permission denied when opening PDF docs with Acrobat Reader X potected mode

[Marcus]

Hi,

this might be off topic because it's not a samba problem, but might be
interesting for others too. We are running an older samba 3.0.24 working
as domain controller (no DFS features). When opening a .pdf file with
the Acrobat Reader X from a WinXP SP3 client (maschine is member of the
domain) the Acrobat Reader X shows a "permission denied". We see the
following in the samba log:

[2010/12/07 18:29:50, 2] lib/access.c:check_access(323)
   Allowed connection from  (x.x.x.x)
[2010/12/07 18:29:50, 2] smbd/reply.c:reply_tcon_and_X(711)
   Serving IPC$ as a Dfs root
[2010/12/07 18:29:51, 2] smbd/open.c:open_file(352)
   user opened file batch.pdf read=No write=No (numopen=1)
[2010/12/07 18:29:51, 2] smbd/close.c:close_normal_file(344)
   user closed file batch.pdf (numopen=0)
[2010/12/07 18:29:51, 2] smbd/open.c:open_file(352)
   user opened file batch.pdf read=Yes write=No (numopen=1)

The user has full read/write permission to the share. The WinXP Sp3
client is member of the domain.

The only workaround in my case is to deactivated the "Protected
Mode" [1] in Acrobat Reader X. All security (enhanced) settings e.g.
privileged locations (L: or \\server\file.pdf etc.) don't have any
effects. This sounds strange to me.

Before rolling out a new reader version to my whole network, any input
on this confusing problem is welcome.

Ciao,
Marcus
