UNIX Password change issue

Hi,

While trying to change the password of a normal user [ I logged in as root], I am getting the following message :-

[root@localhost root]# passwd someuser
Changing password for user someuser.
passwd: Authentication information cannot be recovered
[root@localhost root]#
-------------------
Think there's some issue in PAM configuration for password policy, please guide me for the same. Its urgent.

Thanks

run pwdck command at the command line.
this command will ensure the consistency with all the user authentication files like
1. /etc/security/passwd
2. /etc/passwd
3. /etc/security/login.cfg
4. /etc/security/user

RE: UNIX Password change issue

I would suggest to check for two things:-

1) check for /etc/passwd | grep username

2) edit following file and remove only 'use_authtok' from this file.
# vi /etc/pam.d/common-password
password sufficient pam_ldap.so use_authtok
password required pam_unix.so nullok obscure min 4 max 8 md5

Let me know if this does not solve your problem.
