After installation of RedHat 6.2, using boot image
boot-20000407.img and update-disk-20000419.img
The root-user has still no password. And only user without password can 
log in.

Jul 24 16:45:00 linux login: PAM unable to dlopen
(/lib/security/pam_cracklib.so)
Jul 24 16:45:00 linux login: PAM [dlerror: libcrack.so.2: cannot open 
shared object file: No such file or directory]

module: /lib/security/pam_cracklib.so

by (uid=0)

I tried to install with shadow or md5 enabled or disabled 
During installation I have the message passwd: Module is unknown
and after installation if I run passwd (under root or any user) I have the 
same message.

Do you have the "cracklib" package installed?

Comment 2 Need Real Name 2000-07-25 06:59:53 UTC

Solved.

When I looked in the /tmp/install.log I saw "cracklib installed" and no error 
or warning. But the rpm file was corrupted.
When I checked the package on my cdrom with rpm I got "does not appear to be a 
RPM package"
I downloaded the package and installed it. Now it works.

I have installed another linux with the same cdrom the day before and it was Ok.

This is not a security problem but an installer problem. 
The install log didn't reports any errors. The installer just writes cracklib 
installed even if the package was corrupted !
