Attribute filtering with regex problem

[John Horne]

Hello,

(Using Freeradius 3.0.13)
I have been modifying our 'mods-config/attr_filter/post-proxy' filter file to
allow through a couple of 'Service-Type' attribute values after proxying.
However, to allow more than one value the only way I can get it to work is to
specify the value as 'ANY'. (Running 'radiusd -X' shows the access-accept
packet being sent out with the attribute.) In particular, I have been trying to
use a regular expression but the attribute always gets filtered out.

This works:

  Service-Type =* ANY,

I have also tried:

  Service-Type =~ /Framed-User|Login-User/,
also
  Service-Type =~ "Framed-User|Login-User",
also
  Service-Type =~ "/Framed-User|Login-User/",
even
  Service-Type =~ Framed-User|Login-User,

These all failed. Running 'radiusd -X' showed no error or warning with the
filter files syntax for the entry, but showed the acess-accept packet being
sent out without the attribute. I finally repeated the above regex entries just
using 'Framed-User' (in case the '|' was causing a problem). These too caused
the attribute to be filtered out.

So my question is, what is the correct syntax for using '=~' with a regex in
the post-proxy filter file?



Thanks,

John.
