What is the correct way to use default auth?

I've managed to get default auth to work for pages which require partial protection. However for pages that have full protection (ie have $perm->check near the top of the page) they dump me to the permission denied page (presumably because 'nobody' has no permissions). My question is for pages that require full protection should I be using a different auth class (which I guess would be the same as my usual auth class but with the var $nobody unset), OR should I not be using $perm->check at all but use some different perm check code (ie write my own)? thanks - Jason Wong Digital View Ltd 2201 Nanyang Plaza 57 Hung To Road Kwun Tong HONG KONG Tel: +852-2861-3615 Fax: +852-2520-2987 www.digitalview.com
