This would be because they're not counter-signed by some authoritative source that they trust. Anybody could create their own certificates, so you can't "trust" self-signed certificates, directly. You'd need to have a trusted third party counter-sign them, one that your clients already know about (verisign, etc.), or manually trust such certificates on the clients that are using them (I've no hints on how to do that). The first option costs money, and the latter requires that users know what they're doing (including, having the sense to check that they're trusting YOUR certificate, and not a forgery). -- (Currently running FC4, occasionally trying FC5.)
