FC2 all logins fail

Hi,

My workstation is rejecting all logins: help!

After I logged in this morning I tried to change my account password but got "Authentication token manipulation error".

Now I can't log in as any user including root (Login incorrect). Fortunately I've got an existing login which I can use but unfortunately I haven't got very far with this.

I have two Samba mounts and I've realized the NT account password changed yesterday so I'm intermittently getting smbfs errors. Could this have some bearing?

My workstation runs services for other users and I'm nervous about restarting in case I can't log in ever again!

Very (very) grateful for any assistance.

Thanks for your post.

I'm away from the workstation right now, but I'm using the default authentication i.e. local passwd and shadow files.

"Now I can't log in as any user including root (Login incorrect). Fortunately I've got an existing login which I can use but unfortunately I haven't got very far with this."

So you mean you cant login any user apart from "an existing one"? What is the user you can login as and whats different about it?

No, I mean I've got two *already* logged in sessions from before this problem occurred.

I can't log in any additional sessions and my assumption must be that if I restart or log out any of these sessions I won't be able to log back in.

Have you tried using su to convert one of the logged in users to root? I wouldnt worry too much about restarting - if you have physical access you will always be able to boot in single user mode. If you cant boot into single user mode your system is in pretty bad shape anyway.
http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-rescuemode-booting-single.html will tell you how to boot in single user mode. Its for redhat but applies to fedora as well.

That's what I wanted to hear!

I've restarted now and I can log in fine.

Can anyone posit an explanation? I've never had this problem before.

The error appears to occur when there is a user defined in /etc/passwd which doesnt have a corresponding entry in /etc/shadow. However as a reboot solved your problem that doesnt seem to be the case here. Anyway, pwconv is a program which would fix this .
