Sebastien,

Here is the steps that I did:
1/ Verify that /etc/samba/sbm.conf has the line: security=user
2/ Create a share on my folder /home/myname/Public. I right licked on the folder and select Sharing Options and then check the box "Share this folder"
3/ Go to another computer that has Hardy desktop installed. Open Nautilus and hit Ctrl-L to enter smb://samba-host-ip
4/ I will get a password dialog and after entering proper username and password, I will get access to the Public share as expected.
5/ Now unmount this samba share.
6/ Go to the samba server computer and edit the smb.conf file to change to "security = share", then "sudo /etc/init.d/samba restart"
7/ Go back to the Hardy desktop computer and enter the same "smb://samba-host-ip" this time you will get an empty window, no share listed. But if you enter "smb://samba-host-ip/Public" then you will get the password dialog.
8/ Enter the proper password dialog here and you will get the "Failed to mount..." error dialog.

Hope this help you recreate the problem. I am sure hope to have this bug resolved soon! Let me know if you need more info.

Cheers,

again the authentification issue is different of the "unable to mount"
issue which is described there and is bug #207072

I tried to set security=share yes and to connect to user directories
using the password set using smbpassword and that work correctly,
setting security=share doesn't set any share though and I'm not sure how
to define a share and set a password then, could somebody who knows that
describe how to set up a share clearly?
