[SOLVED] Password synchronization failed in passwd command

antriksh · 07-15-2015, 12:59 AM

Hi,

When i am trying to change the password for a user it is failing as below:

Code:

[root@el01cn01 sm250564]# passwd pp250207
Please type a new password:
Please re-enter the new password:
Synchronizing Password...
password synchronization failed.

Changing UNIX password...
OK
The password has been successfully set.

[root@el01cn01 sm250564]# id pp250207
uid=105(pp250207) gid=105(pp250207) groups=105(pp250207)

[root@el01cn01 sm250564]# uname -a;date
Linux el01cn01.daytonoh.ncr.com 2.6.32-400.34.1.el5uek #1 SMP Mon Dec 23 07:49:47 PST 2013 x86_64 x86_64 x86_64 GNU/Linux
Tue Jul 14 12:51:45 EDT 2015

Code:

/etc/nsswitch.conf:

passwd:     files
shadow:     files
group:      files

#hosts:     db files nisplus nis dns
hosts:      files dns
netgroup:   nisplus
publickey:  nisplus
automount:  files nisplus
aliases:    files nisplus
sudoers:  files ldap

What could be the reason for password sync failed error?

Maybe check the log for selinux errors.

Also check the Dayton Hamfest for tubes. I'm down to my last 6AU6.

selinux is disabled.

I think permission for passwd should be

-rw-r--r-- 1 root root 1515 May 3 17:52 /etc/passwd

This is the issue. Can some one confirm?

My /etc/passwd

Code:

ls -l /etc/passwd
-rw-r--r-- 1 root root 2093 Jun  9 09:31 /etc/passwd

Tried changing the permission but didn't work:

Quote:

[root@el01cn01 sm250564]# ls -l /etc/passwd *
-rw-r--r-- 1 root root 7658 Jul 15 13:07 /etc/passwd

-bash-3.2$ sudo passwd pp250207
Please type a new password:
Please re-enter the new password:
Synchronizing Password...
password synchronization failed.

Changing UNIX password...
OK
The password has been successfully set

-bash-3.2$ su - pp250207
Password:
su: incorrect password

Also check:

Code:

ls -l /etc/shadow
---------- 1 root root 852 Jul 15  2015 /etc/shadow
ls -l /usr/bin/passwd 
-rwsr-xr-x. 1 root root 30768 Feb 22  2012 /usr/bin/passwd

antriksh · 07-15-2015, 12:58 PM

Code:

[root@el01cn01 sm250564]# ls -l /etc/shadow
-r-------- 1 root root 6028 Jul 15 09:01 /etc/shadow

Thinking of getting strace for passwd. What else i can look into?

Somehow it was determined that /usr/bin/passwd was corrupted and replacing it from other working server resolved the issue.
