This certificate was signed by an unknown authority

Hi, Have created the p.12 Development and p.12 Distribution certificates. Now got to testing certificates in Adobe 'Step by Step guide to dps'. Hit brick wall. In key Chain Access, in Login: The certificates iphone Developer and iphone Distribution relating to keys say in the pane above 'This certificate with signed by an unknown authority' with a red cross at the side.

Going by the guide, it should have a green tick and say 'This certificate is valid' so I deleted all certificates & keys and started again, being extra careful to do all the steps correctly. BUT, still same message 'This certificate with signed by an unknown authority'.

The only explanation I could think of is that my collegue set up the Apple ID & enrolled in the iOS Dev prog for our company on another Mac. I used the Apple ID he set up to create the certificates on my Mac - on which I'm going to create the single edition app. Would this affect the certificates validation?

Please help & thank you in advance!

NOW SOLVED! If anyone else has this issue, here's the fix:
The problem was missing apple WWDR intermediate certificate.
You must also install the WWDR intermediate certificate issued by Apple’s worldwide developer relations. It can be downloaded from the portal or directly athttp://developer.apple.com/certificationauthority/AppleWWDRCA.cer Make sure you add this to your keychain as well.

Hi there barringtondesign, Great stuff, thank you. Yep, this little nugget of info appears to be missing from the Adobe Step by Step Guide - I guess they'll be a few people getting stuck at this point.
Hopefully they'll include it in an update soon.
Good luck with your apps!

The WWDR imtermediate certificate should be installed automatically when you install Xcode. The publishing guides state that if you don't install Xcode, you need to manually install both the WWDR intermediate certificate and the Application Loader.

The new guides are uploaded now.

Thanks Bob
I had downloaded it but just forgot to open it for the first time so that it was actually installed and not just on the Launchpad
