safari and https certificates


HampCake Studios
i'm using a https connection to manage a remote linksys router, the certificate is not valid as the router uses an open source firmware and not the original one from linksys, so safari warns me about the problem

if i check the "trust always this certificate" option, safari continues to ask me if i want to trust it

i'm using safari 2.0 (412.2) on osx 10.4.2

what's the problem?
