If you provide the PAM configuration, we can try to reproduce it.

This usually means files like:
 * /etc/pam.d/su
 * /etc/pam.d/common-auth
 * /etc/pam.d/common-password
 * /etc/pam.d/common-session
 * /etc/security/pam_env.conf
 * /etc/security/limits.conf
 * /etc/pam.conf

Note that there may be sensible information in them (just filter out some
fields if you wish).

You can also check if it is caused by a file corruption:
debsum login libpam0g libpam-runtime libpam-modules
(and maybe other packages)

Kind Regards,
