pfauth on 5.4

[Sven Meier]

Hello,

I'm using pf on FreeBSD 5.4 and was thinking of using pfauth to  
secure access from my wireless network.  Somehow I don't seem to find  
much documentation about pfauth on FreeBSD.  Has it not been ported  
along with PF itself?

If not, can anyone recommend an alternative with similar functionality?
I've been looking around for this for while now so any help with this  
will be much appreciated,

Sven.
