Subject: [PATCH] pam_unix: do not use crypt_checksalt when checking for
password expiration
According to Zack Weinberg, the intended meaning of
CRYPT_SALT_METHOD_LEGACY is "passwd(1) should not use this hashing
method", it is not supposed to mean "force a password change on next
login for any user with an existing stored hash using this method".
This reverts commit 4da9febc39b955892a30686e8396785b96bb8ba5.
* modules/pam_unix/passverify.c (check_shadow_expiry)
[CRYPT_CHECKSALT_AVAILABLE]: Remove.
Closes: https://github.com/linux-pam/linux-pam/issues/367
