GoDaddy SSL Nightmare…. Buyer Beware….

OK So I purchased 3 SSL certs from Go Daddy for 3 servers. I installed as per instructions. None of them work, at all… GoDaddy initially said it was my problem but it certainly is not. There seems to be no Root certificate from Go daddy that works and as such users get the warning when ever they connect… For over £200 I have got a system which seems more broken than our original self signed certs… Go daddy swear no one else has this problem which I guess is a lie since I have since found may many posts about this… So assuming Go daddy will never work, which certificates work out of the box on leopard + Snow leopard + iPhone ? Maybe we can fix this ? Has anyone ever managed to fix Go Daddy Certs ? The Certificate from Go Daddy was generated from a Self Signed server certificate on. I have 3 servers I am struggling with with this… any suggestions most welcome… I want to be able to just apply a bona fide Cert to the system an d all service to just work… Thanks for any help in advance….
