           Summary: Can't run SourceSafe over samba mount

Hi,

Until maybe a year or so, I used to be able to use SourceSafe with the
executable on a mounted samba share. Then one day, it started failing after the
authentication dialog.

I get a Microsoft Visual SourceSafe dialog which says "Invalid Handle" and a
winerserver message on the console which says: "file_set_error() can't map
error: Operation not supported"

Here is my environment in Fedora 24:

${HOME}/gvfs is a symlink to /run/user/uid/gvfs
${SSAFE} is set to
"${HOME}/gvfs/smb-share:domain(...)/SourceSafe/somedir/vss6/win32/SSEXP.EXE"

When I run `wine "$SSAFE"` (which again used to work until fairly recently), I
get the Visual SourceSafe Login dialog and the "Invalid Handle" error.

$ rpm -q wine samba
wine-1.9.23-2.fc24.x86_64
samba-4.4.7-2.fc24.x86_64
