How do I add another developer's certificate to the iOS provisioning portal?

Question

I've been trying to enable another developer on my team to build an iPad app that we are creating for a client, but am having no luck getting his development certificate uploading into the provisioning portal.

I'm starting to think I'm missing something simple. My assumption is that each developer needs to have their own certificate listed on the Certificates -> Development page. Is that right, or are we supposed to be using only one certificate?

We tried setting him up with the certificate that's currently listed, but he gets "Error: "A valid signing identity matching this profile could not be found in your keychain" when trying to build.

Though I had licked this provisioning thing, but I guess not :)

Thanks for any help you all can offer.

You need to invite the developer to your account in the apple developer site.

Member Center > People > Invitations > Invite a Person to Your Team

This should automatically install their developer profile and then you can sign the app with the "Team Provisioning Profile".

Also check out Organizer > Provisioning Profiles > Automatic Device Provisioning in Xcode 4; this simplifies installing profiles.
