CentOS 6 - NIS - User Password Reuse Message Client System

[gamradtk]

I recently migrated (2) new servers to CentOS 6 from Fedora 14. Fedora 14 has compatibility issues with IBM x3550 M3 servers and ServeRAID M1015 controllers. Hopefully CentOS 6 will not break for the same reason.

I have (1) CentOS 6 server (NIS and NFS for sharing user accounts).

I have (1) CentOS 6 client server and (1) Fedora 13 CUDA client server (non-IBM).

All systems have newest kernel and updates for that distribution.

When a user requests a password change on the Fedora 13 client box everything works as expected.

When a user requests a password change on the CentOS 6 client box it states that the user cannot reuse the previous password even if the previous password was not entered.

All files are consistent:

/etc/libuser.conf
/etc/login.defs
/etc/nsswitch.conf
/etc/yp.conf
/etc/pam.d/password-auth
/etc/pam.d/system-auth
/etc/sysconfig/authconfig
/etc/sysconfig/network

Using sha512

ypbind is running on clients

yppasswdd and ypserv are running on server

User accounts (> 500 not including nfsnobody) migrated from Fedora 12 server (passwd and shadow - no special groups)

UPDATE
=====

I should add that I do not have a policy enabled that restricts using old password.

Thanks in advance!!!

Additional Information:

Firewall and SELinux are both disabled on all systems.

My Fedora 14 x86_64 Virtual Machines created using VMware Workstation 7.1.4 can both log in and change passwords through NIS and NFS.

Short Term Workaround:

I copied the /usr/bin/yppasswd file from my Fedora 14 Virtual Machine to the CentOS 6 client server and now it can change passwords.

I'm still hoping that there is a better solution out there to be found...
