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.
