Report

This is similar to #561 and #562.

Using pam_authenticate function call to grant access to a user can cause security issues. A pam_authenticate call only checks if the username and the password match. It does not check if the account is expired. Hence, a user with an expired login or an expired password can still login.

This PR aims to detect instances were an initiated PAM Transaction calls pam_authenticate but does not call pam_acct_mgtmt.
