It's what I do... I'm not *always* cranky...
I am using the debian packages (currently 3.0.16+dfsg-1+b1 from the unstable release) and I'd love to keep this approach (because of the updates). I don't know how exactly the maintainer compile the FR packages, but i would not expect the pcre support as enabled during the compilation. Does exist any other way for me how to enable the pcre support ?
Install the pcre development headers. Then build FreeRADIUS from source yourself. Instructions are on the wiki for building a debian package.
Or, use another method to parse the Cisco-AVPairs. e.g. rlm_perl.
This turned out to be ideal. Howerer, passing request to the perl script fails on the same thing - attributes are passed empty aswell.

Hmm... I guess that expansion isn't binary safe. Oh well...
Or, use the "unpack" module to unpack binary data. See raddb/mods- available/unpack for documentation.
I did.
I tried
if (&Cisco-AVPair) { foreach &Cisco-AVPair { if ("%{unpack: &Foreach-Variable-0 0 short}" =~ /${policy.device_regex}/i) {} }
That won't work. The Foreach-Variable can't be passed in expansions like that. Plus, even if it did work, you would be unpacking the first 2 bytes of the value. Which are ASCII, and not the number you want. Alan DeKok.
