Ah, so that seems to have worked; the problem is doing a regexp match on 
an "octets" attribute, which is converting it to hex first, and that's 
not what you want.

You could as a temporary workaround try putting an override in your 
local dictionary (raddb/dictionary):

ATTRIBUTE     Class                                   25      string

That should work because I ended up doing exactly that a long time ago 
with FreeRADIUS 2.1.

Otherwise in 3.0 it might be possible to try casting, e.g. 
<string>&Class, but I'm not sure if that will also give you the hex 
encoding.
