I just re-connected the build server with our development team. This made the Xcode-service to re-initialize all certificates and provisioning profiles it needs. Now the integration builds run without errors.
In Server > Xcode > Settings > Builds > Development Teams click on Edit...
Remove your development team(s) from the list and press OK
After ther Server.app finished its work, there should be no entry behinde "Development Teams" and the list of devices is also empty.
Now open Server > Xcode > Settings > Builds > Development Teams > Edit... again and add your development team
After your team and devices re-appeared, you can start the integration build
It's important not to use your own provisioning profiles. Take the "iOS Developer (Automatic)" setting.
