pam_loginuid - Record user\'s login uid to the process attribute

pam_loginuid.so [require_auditd]

The pam_loginuid module sets the loginuid process attribute for the process that was authenticated. This is necessary for applications to be correctly audited. This PAM module should only be used for entry point applications like: login, sshd, gdm, vsftpd, crond and atd. There are probably other entry point applications besides these. You should not use it for applications like sudo or su as that defeats the purpose by changing the loginuid to the account they just switched to.

require_auditd
    This option, when given, will cause this module to query the audit daemon status and deny logins if it is not running.

Only the session module type is provided.

PAM_SESSION_ERR
    An error occurred during session management.
