somehow i got the same problem like in this question: Validating fails because of account permissions
We got a valid distribution certificate with private key and with the new automatic code signing in Xcode 8 everything works fine while developing. But when we try to upload an archive to itunes connect only a admin is able to do it. And for every admin we have to create a new distribution certificate. Normal Members always get the message: Your account does not have permission to create iOS distribution certificate even if a valid cert is in the keychain.
So my question: how do we have to setup Xcode 8 with automatic signing to work with one distribution cert, independent of the account role?
