addition to policy.conf

hi, a little something that I've been meaning to send out for a while. basically, a small addition to policy.conf (that probably could do with a few little extra additions) that will allow sites to easily check for NAI 4282 compliance - simply, that a User-Name is valid for proxying to other locations - a great boon for sites using eduroam , for example, as it stops end sites filling up the heirarchical proxy system with junk requests.... many sites have a lot of messy rules in place...with this addition to policy.conf all they need to do is call check_nai_compliance in their authorize section and things are nice. attached (should be all okay for 2.1.13 and 3.x ) alan
