When kadm5_add_passwd_quality_verifier is called with a NULL check_library parameter and [password_quality].policy_libraries is set, the function calls add_verifier() for each string in the policy_libraries section and then falls through to the non-NULL case and calls add_verifier() a final time with a NULL argument. This leads to dlopening the running executable and then failing since it contains no password quality verifier. If the check_library argument is NULL, only call add_verifier() for the configured policy_libraries and do not fall through to the non-NULL case. Signed-off-by: Love Hornquist Astrand <lha@h5l.org>
