RE: problem with proxy_auth

try

authenticate_program /usr/local/sbin/check-auth-system.pl
acl extauth proxy_auth REQUIRED
acl localnet src 192.168.0.0/24
http_access allow localnet
http_access allow extauth
http_access deny all

----------
http_access allow uses "AND logic"

"http_access allow localnet extauth", means localnet AND extauth and nobody
match this rule.
