I can't login to fedora 11 .

Zen alsory · 02-12-2010, 11:11 AM

I have a cluster consists of 4 computers..These computers were working well before 2 months,and for last 2 months they were switched off .
When I switched them on again they (all) refuse the password and I get "unable to authenticate the user" every time I try to login to any one of them ...!!
I used the terminal (alt+ctrl+F2) to make sure that the password is correct and it was ..!!
Then I added new user and it couldn't authenticate the new user too..!

So, Where is the problem ?
What I have to do to be able to login again ??

Code:

login: root
password:<hashed>
#passwd <locked out user>
New password: < enter new hash>
<confirmation> :<repeat hash>
<confirmation of update>

Are these machines authenticating against an LDAP server or are they local accounts only? Can you login with the local root account?

They are local accounts , and I can't login as root in fedora 11 ..
I can login as user or as root by using the terminal(alt+ctrl+F2).

So you are having issues logging into the GUI because you can login to the terminal.

Are you receiving an error when you try to login to the GUI?
Which X environment are you using?
Have you tried to reinstall the X environment?
What about deleting the x config files for the user accounts that are unable to login? For gnome this should be /home/<username>/.gconf and for KDE it will be stored in /home/<username>/.kde/share/config/

That wont fix the problem. The problem is with X authenticating. He can login as root under CLI, just not in GUI

oh... i didn't read the post properly

try logging in via GDM/KDM a couple of times, then drop to the shell and check /var/log/messages, /var/log/secure, /var/log/gdm/*

deleting files or reinstalling should be a last resort

Good point, I forget I am working with people that may or may not have less experience than me and assumed the logs had been checked. My bad.

Zen alsory,

Have you perhaps done a yum update or even a yum upgrade recently? I believe that a recent change in Fedora 12 blocks GUI logins for the root account and if you have performed any updates this maybe the reason.

You make it sound like a job
