Logging in as pi reprompts

[robot]

When I log in as pi and use the correct password, it prompts me again for username. The usual log in output comes up when I do this. Then it asks again for user name. Why can't I login as pi?

The configure script is known to corrupt the SDcard sometimes, re-image and try again.

So if I re-image, I lose everything that I've put on there?

Have you installed anything since the last successful login?

how about logging in via ssh

I've tried logging in through putty and putty just closes immediately and I've tried restarting the pi and logging in directly to the pi. I haven't installed anything. I can login through another user account but this doesn't help me a whole lot since pi is the only user with root permissions.

Before the problem occurred, I was remoting in on a desktop. I think that I left my putty session on when I went home and then tried to remotely connect through a laptop. This is when the problem started. It should kick pi off the other desktop session right? When I went back to my desktop, the session showed as (inactive) and I closed it.

I then logged in as non-pi user and tried to see who was logged in. It showed that pi was still logged in so I rebooted the pi. Now pi was not logged in but the problem still occured.

The only other changes that I was making to the pi at the time was to the smb.conf. I changed the top contents from another user to pi as follows:

[pi]
commment = pi folder
path = /media/USBHDD1/shares
valid users = @users
force group = users
create mask = 0660
directory mask = 0771
read only = no
