By default this file /etc/pam.d/common-password has this conf for password change:
password [success=1 default=ignore] pam_unix.so *obscure* sha512
However the Journal shows that Obscure is not parsed as an argument. What Obscure does is to set some extra simple checks to the password.
The reason is the fetch libpam package is missing the patches to setup Obscure.
As a comparison point, download this tarball, contrast it with WR's platform project, and notice the patches with Obscure source file, its methods, and argument definition for PAM Unix module.
