NAME

6       pam_loginuid - Record user's login uid to the process attribute
7

SYNOPSIS

9       pam_loginuid.so [require_auditd]
10

DESCRIPTION

12       The pam_loginuid module sets the loginuid process attribute for the
13       process that was authenticated. This is necessary for applications to
14       be correctly audited. This PAM module should only be used for entry
15       point applications like: login, sshd, gdm, vsftpd, crond and atd. There
16       are probably other entry point applications besides these. You should
17       not use it for applications like sudo or su as that defeats the purpose
18       by changing the loginuid to the account they just switched to.
19

OPTIONS

21       require_auditd
22           This option, when given, will cause this module to query the audit
23           daemon status and deny logins if it is not running.
24

MODULE TYPES PROVIDED

26       Only the session module type is provided.
27

RETURN VALUES

29       PAM_SUCCESS
30           The loginuid value is set and auditd is running if check requested.
31
32       PAM_IGNORE
33           The /proc/self/loginuid file is not present on the system or the
34           login process runs inside uid namespace and kernel does not support
35           overwriting loginuid.
36
37       PAM_SESSION_ERR
38           Any other error prevented setting loginuid or auditd is not
39           running.
