Centos5 user locked out

Hey there,

Centos5 noob.  

I have a user who isn't able to log on to the domain.  I reset his password and he still isn't able to login.  I'm assuming that he's been locked out due to a lockout policy.  

How do I reset his user so he's not locked out.  I would need to do it via command line since the GUI users and groups application won't open (it prompts me for root credentials and then just doesn't open).

ANy help will be greatly appreciated.

Use the following command

chage -l

This will show you if it is locked.

Also, you can get the entries of this user in /etc/passwd and /etc/shadow files.  If there is a ! in front of the password hash of this user, you will have to get rid of it.

Thanks Farzanj,

The output for chage -l is as follows:

Last password change: Mar 12, 2012
Password expires: never
Password inactive: never
Account expires: never
Minimum number of days between password change: 0
Maximum number of days between password change: 999999
Number of days warning before password expires: 7

Does this indicate that he's not locked out?

Run the command
grep "userID" /etc/passwd
grep "userID" /etc/shadow

Just change the userID info but show the rest of it.

It looks fine.

Now here is how I would troubleshoot it.

1.  As root, try to su - to this user.

#whoami
root
#su - myuser
whoami
myuser

Successful?

2.  Open another console and try to log on directly to this user without using root.
Successful?

If not, change the password hash in /etc/shadow file.
I generated hash for password "password"

# grub-md5-crypt
Password:
Retype password:
$1$75nSY0$khv7ghFoAEHjIOtztHbqv0

myuser:$1$75nSY0$khv7ghFoAEHjIOtztHbqv0:15411:0:99999:7:::

And try to log on.  Success?

3.  Is the user trying to log on remotely?  Using ssh?  He may be restricted in ssh.

4.  Are you by any chance using LDAP for user authentication?

I am able to su to myuser and also to ssh as myuser without trouble.

The user is trying to log on to the samba domain from a windows7 pro computer.  He has done this successfully (as have other users) without issue for over a year.  The win box went down over the weekend for an automatic update and he's not been able to login since.  

I had him verify that he's loging in as domain\myuser but still no joy.  

Any other ideas?

Oh, then it is a totally different issue.  It is related to Samba now.  On windows side he lost something.  You will have to check the windows part.
