No signing certificate iOS Distribution

Question

I'm having trouble generating an IPA for OTA distribution.

We made an app for another company. That other company added me on their Enterprise account so that I could distribute using their signing identity.

Creating the ipa with the command line

Using the command xcodebuild, an archive I made using xcode where I put the team as that other company's team, and a plist stating I was building for Enterprise, I get this error:

No valid iOS Distribution signing identities belonging to team [company team id of the other company] were found.

Using XCode

I tried doing it with XCode as well, unchecking the "Automatically manage signing" in Xcode and selecting the other company, and then I get these errors:

No signing certificate "iOS Distribution" found.

No "iOS Distribution" signing certificate matching team ID [other company's team ID] with a private key was found."

Is there something I should download from the developer account? (I already downloaded all the certificates... I think) I can't revoke the distribution certificate they have, as it is not my company and it might create problems for them.

Thanks.

When you downloaded every certificate from the developer account, you only downloaded the public keys, what you need to do is one of two solutions that I know of:

Either ask the other company to export one of the private key from one of their machine, and you can import it into your keychain, only then when you'll try to sign your app, it will look for private half of the certificate in the keychain and it will find it (hence the error you're getting, no certificate with PRIVATE KEY was found).

Or, you'll have to create a new production Certificate using a certificate generated from your own keychain (and a provisioning that goes with it...).
