Hi

You have a missing package.

liblaus

add this and give it a shot.

It looks like the pam_cracklib.so file can't be openned. Ensure that the pam files are correct by using:

rpm -V pam

I see input/output error, if the file exists, check if you can read its contents:

strings /lib/security/pam_cracklib.so

If you get I/O error, maybe some corruption exists.

shalom,

I think Ivan is right and you can re-install pam or cracklib to fix this.
