I'm working with Xcode 4.1 build 4B110f trying to get my iOS app ready for upload. It passes the Product|Archive step with no errors, asking twice for permission to sign something. But when I try a validate of the archive from the Organizer, it fails:
### Codesigning '/Users/uqrchern/Library/MobileDevice/Provisioning Profiles/70D2381D-3733-4F5D-88B2-4729572C2864.mobileprovision' with 'iPhone Distribution: Ron Chernich'

error: codesign failed with error 1
I've looked at all the similar problems and solutions (some of which make no sense whatever, or apply to really old versions of the tools). None have made the slightest difference.
I've also checked 3 times that verify is using the "production" certificate, as is the codesign step that produces the archive. I've even turned the above output into a schell script so I could try all certificates manually: same result every time.
Maybe the .app file being signed really is unsuitable?
Incidentally, codesign has no version flag, but the man page is dated June 1 2006. The binary has a file date of Nov 20 2010.
UPDATE (next day):
Researching the problem further found an obscure reference saying that codesign needs the following environment var set:
CODESIGN_ALL
