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 02:59:53 EDT

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 !
