.SH "NAME"
pam_loginuid \- Record user\*(Aqs login uid to the process attribute
.SH "SYNOPSIS"
.HP \w'\fBpam_loginuid\&.so\fR\ 'u
\fBpam_loginuid\&.so\fR [require_auditd]
.SH "DESCRIPTION"
.PP
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\&.
.SH "OPTIONS"
.PP
\fBrequire_auditd\fR
.RS 4
This option, when given, will cause this module to query the audit daemon status and deny logins if it is not running\&.
.RE
.SH "MODULE TYPES PROVIDED"
.PP
Only the
\fBsession\fR
module type is provided\&.
.SH "RETURN VALUES"
.PP
.PP
PAM_SUCCESS
.RS 4
The loginuid value is set and auditd is running if check requested\&.
.RE
.PP
PAM_IGNORE
.RS 4
The /proc/self/loginuid file is not present on the system or the login process runs inside uid namespace and kernel does not support overwriting loginuid\&.
.RE
.PP
PAM_SESSION_ERR
.RS 4
Any other error prevented setting loginuid or auditd is not running\&.
