Hello,
I just did a fresh install of 12.04, 64 bit and have a problem with Nautilus. A samba share that I used to connect to regularly on my LAN now does not work within Nautilus. When I click on the bookmark (or do it from scratch via File->Connect to Server) I get asked for username, workgroup and password. When I enter the credentials and press connect, the credentials window closes and then opens again, asking for the information again. This happens endlessly.

I can mount the share using
Code:
sudo mount -t cifs -o username=user,password=pass //XXX.XXX.XXX.XXX/data_user/data /media/samba
and then go from there, but I'd like the GUI way to work too.

Any idea of what could be going on?

Thanks!
