Description of problem:
Issue: 
The customer has imposed a secure password policy using the following
system-auth config:


                                                                     
          
password    sufficient    /lib/security/pam_unix.so nullok use_authtok
md5 shadow remember=12

The problem lies in the fact that the documentation in
/usr/share/doc/pam-0.75/README.pam_unix clearly states that remember
can be used to save passwords in /etc/security/opasswd for enforcing
password uniqueness.
This functionality does not work.


Version-Release number of selected component (if applicable):
pam-0.75-46.7.3

How reproducible:
Always

Steps to Reproduce:
1.Edit /etc/pam.d/system-auth adding remember=5 debug
2.attempt to change a users password
3.check /var/log/messages and the debug error reports remember as an
invalid option
