Comment 159 for bug 209520

Steve, to be sure I just tested 9.04 alpha4 in VirtualBox

gvfs-mount smb://user@server/my-share
Password required for share my-share on my-host
User [myuser]:
Domain [MSHOME]:
Password:
Error mounting location: Failed to mount Windows share

After changing
security = share
to
security = user
in smb.conf on a server and restarting samba, I'm trying again:

gvfs-mount smb://user@server/my-share
Password required for share my-share on my-host
User [myuser]:
Domain [MSHOME]:
Password:

At this point my-share is mounted and all is good, but windows users can't connect to this server anymore
cmd->net view server
cause an error and I have to revert smb.conf changes.

I am sure the same happend with 8.10, when I tried it a week ago and then I found this bug and subscribed to it.
HTH.
