This is the record emitted by the kernel to say that the user's loginuid has
changed. This would mean that pam_loginuid was run. But the event is being
sent by the kernel, not pam.

Because that is not an event of interest in prelide right now.

Nope...somewhere the pam originating events are being eaten. You might strace
an xdm login and look for some sendto's followed immediately by recvfrom's to
the audit socket. If they are missing entirely, then xdm is not calling pam.
If they are there, we'd want to look at the return code to see if its having
an error. Is xdm running as root at the point pam is called? Are there
selinux rules? Are there dontaudit rules eating this?
