In the initWithIdentity:certificates:persistence: method, what is the purpose of the certificates argument? The identity has a certificate associated with it, so which other certificates am I expected to pass to this call? The server is not accepting my certificate, and I suspect it is because I'm calling this wrong. This is my callba...

My goal is to have the outline view h...
