We are using an enterpise-account for our apps, but it is only possible to create a maximum of three certificates. So far I have always used my own. But now I have to take one of the distribution certificates prepared by the company. I'm assuming the certificate is now missing my CertSigningRequerst.csr, right? How do I have to proceed so that I can use the new certificate? Thanks for the support.error: Missing private key for signing certificate. Failed to locate the private key matching certificate "iPhone Distribution: Laxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" in the keychain. To sign with this signing certificate, install its private key in your keychain. If you don't have the private key, select a different signing certificate for CODE_SIGN_IDENTITY in the build settings editor. (in target 'B4iProject' from project 'B4iProject')
