Unhappy Please Help Change Password Min Length from 6 to 8


After googling for days and calling Red Hat (1888REDHAT1) I'm need help. I have gone to various webistes including this theb belwo https://bugzilla.redhat.com/show_bug.cgi?id=17487


If I modify the /etc/pam.d/system-auth
password requisite /lib/security/$ISA/pam_cracklib.so retry=3
minlen=8 lcredit=-1 ucredit=-1 dcredit=-1 ocredit=-1

If I modify the /etc/pam.d/passwd
password required /lib/security/pam_cracklib.so retry=3 minlen=8

If I modify the etc/login.defs and change MIN to 8 still nothing.

Can anyone tell me if they got it to work modifying one of the files above and which?

Using RHEL Workstation 4 64bit 2.6.9-5 ELsmp

Did you do this?

"Now verify that the new password restrictions work for new passwords. Simply login to a non-root account and change the password using the passwd command. Note that the above requirements are not enforced if you run the passwd command under root."

Unhappy Attempts to test Min Password Requirement

After modifying the files I chage a few other security realivent files and rebooted the system. Now my Linux Box will not boot properly, constantly switch view between the login splash screen and NIVIDA (in a do-loop). I'm not sure if modifying the password files or adding a password hash to the /sbin/grub/grub.conf file broke my system. I will probably be forced to reload Linux.

If my memory serves me correctly, since I have done so much over the last few days on this issue, I want to say yes users could change there password with less than 8 characters.

I have called Red Hat and they refer me to bugszilla.redhat.com. I have read the Linux internal shared documents found on the Linux box under somthing like user/share/documents/..... and even followed their directions to the T and copied and pasted the commands but to no avail.

Once I rebuild the system, as I suspect I will have to, I will avoid change the /sbin/grub/grub.conf file untill I resolve this password issue.
