iOS Provisioning Portal - 2 developers - provisioning profiles invalid for one developer

Question

I can't figure out what the correct way of working with the Provisioning Portal is. Here is our situation:

• 2 developer accounts, 2 different computers, same team
• one certificate in Provisioning Portal > Certificates > Distribution. The certificate includes two distribution profiles

My problem is that the two distribution provisioning profiles are always invalid for one of the developers. We got into that situation by "starting fresh": revoking both development and distribution certificates, then creating new ones from either of the developers' machines. As soon as new certificates are created, the provisioning profiles become invalid. I guess I understand why that happens. What I can't understand is how to do everything so that both developers can work with valid certificates.

Answer 1

have one of the developers export his certificate from the keychain, along with it's private key and send it to the other one. Should work fine that way for both.
