This is probably not the cleanest way do to it, but from your pam module 
you should be able to find the fd which is the socket being used (if you 
are lucky it will always be the same number) and then query the address 
yourself.

I don't know off hand how you would do that but it is possible.  Check 
lsof and see how it does it (might be an ioctl or might involve /proc)
