@Tilman_PPP - The only thing I can think is that the CA is not trusted by the SA Flash Player. I usually encounter this issue in the browser when using self-signed certs. If the SA FP is anything like the plugin, I think it will reference the OS' cert store to validate. I know on the Mac you can add the cert to your Keychain, but I'm unsure of the mechanism to use in Ubuntu. With a little Google'ing I found these instructions on the Ubuntu help section: https://help.ubuntu.com/8.04/serverguide/C/certificates-and-security.html.
Hope this helps. Let us know how it goes.
Thanks for your response. Unfortunately that didn't do the trick for me. Can anybody tell me which certificate store flexunit/"Flash Player 10.1 Projector content debugger" uses on an Ubuntu 10.04? Or does anybody have another idea to help me out?
The only other suggestion I can make is to launch the tests using the browser and register the cert that way. If that isn't an option then you'll have to post to the FP forums for further help. Let us know how it goes. -Brian
