authpf not working

[Sven Meier]

Hello pf experts,

I'm running pf on FreeBSD 6.0-STABLE.  PF itself works fine, but I  
cannot get authpf to work.  It used to work and after a reinstall  
(and upgrade to the 6 branch) I copied all the config files back into  
their places and now the magic is gone.

I have placed the relevant anchors in my /etc/pf.conf (anchor "authpf/ 
*" and so on) file and created the user files in /etc/authpf/users/.  
When sshing in as an authpf user, I get the following error on the  
client machine.  The server shows just the authpf exited abnormally.

pfctl: /dev/fd/4: No such file or directory
Unable to modify filters
Connection to XXX.XXX.XXX.XXX closed.

I have placed the appropriate permissions on /var/authpf/.

The machine runs a custom kernel to enable pf.  The lines I added are  
as follows - all taken from the handbook.

device          pf
device          pflog
device          pfsync
options         ALTQ
options         ALTQ_CBQ
options         ALTQ_RED
options         ALTQ_RIO
options         ALTQ_HFSC
options         ALTQ_CDNR
options         ALTQ_PRIQ

Can anyone point me in the right direction on how to fix this.

Sven.
