my question is about creating a distribution certificate for an app that will be distributed to company employees only. my assumption is that i should select 'in-house and ad hoc' when i click to create a new certificate. if that's correct, my issue is that when the certificate is created & downloaded to my mac, when i click the mobileprovision file, i only get the public key, no private. i'm wondering if this is because there's an existing distribution certificate that exists in my keychain that does include the private key. can i only have 1 distribution certificate active at a time?
