3.0.x: check regex against multiple instances of attribute

That's the one which concat's all the values into one "huge" attribute,
and you can regex the part you want out of it?

Well the people there can be members of up to some 50 groups, all having
a 100+ character DN. I know that this busted FreeRADIUS 2.x max
attribute length limit, and I guess it might also be too much for the
(2000 char'ish) limit in 3.x.

The foreach however does its job nicely :-) Thanks for the quick
suggestions!

Greetings,

Stefan Winter
