[Samba] Samba mounted home shares will break many applications

[Bob Smith]

I didn't get any responses to my previous post "Wine broken on Samba
shares due to colon ":" filenames" so I am re-posting with a subject to
reflect what I now believe to the the root cause of my problems.

I recently changed from mounting my home directory using NFS to mounting
with CIFS via the pam module pam_mount.so. It turns out that I am having
problems with many applications that are embedding any of the Samba
reserved characters "\ / : * ? " < > |", principally the colon ":". Here
is a short list of applications that I use that embed the colon in files
within their respective configuration directories in the home directory:

Evolution
Wine
Picasa (via wine)
VNC
Opera
Pulse Audio
Nautilus
Rhythmbox (if your track name has a colon)

Possibly many others. Some apps gracefully handle any problems, many
others don't.

I am positive that I have enabled Unix Extensions on my Samba server.
Here is a snippet of my smb.conf for the Samba server serving the home
shares:
[global]
  unix extensions = yes
  case sensitive = yes
  delete readonly = yes

  dos charset =
  unix charset = UTF8

On my client workstation (Ubuntu Karmic Koala (latest)) I have the
following output from /proc/fs/cifs:
$ cat LinuxExtensionsEnabled
1
$ cat DebugData

I would appreciate any assistance with this issue. I will provide
additional information upon request to anyone willing to help me look
into this problem.
