Description of problem: pam_access and pam_time can send audit events when blocking access due to policies violations. There is a new requirement in SP 800-53, AC-2(12) which asks for : The organization: (a) Monitors information system accounts for [Assignment: organization-defined atypical use]; and (b) Reports atypical usage of information system accounts to [Assignment: organization-defined personnel or roles]. Atypical usage includes, for example, accessing information systems at certain times of the day and from locations that are not consistent with the normal usage patterns of individuals working in organizations. What would be helpful is if there was a way to indicate that we want the audit event when there is a policy violation but not to block the access. There may be a legitimate need to allow the login but the security officer just wants to be aware for possible follow up. Version-Release number of selected component (if applicable): pam-1.1.8-18.el7
Thinking about this more - this is actually already possible with the current pam_access and pam_time. You simply configure the PAM stack so the module is called but its return value is ignored.
