command/usr/bin/codesign failed with exit code 1- code sign error

I
spent now 3 hours of searching for the above mentioned error:

Command
/usr/bin/codesign failed with exit code 1

Here
is what I already did for trying to fix this:

set
the bundle identifier to com.server.pgmname
set
the code signing to "Any Iphone OS Device"
set
the Code Signing Identity to my Distribution identity.

The
error only occurs when I try to build on my device, on the simulator everything works fine.

Do
you guys have any suggestions?

Thank
you very much in advance!

I had the exact same error, and tried everything under the sun, including what was suggested elsewhere on this page. What the problem was for me was that in Keychain Access, the actual Apple WWDR certificate was marked as "Always Trust". It needed to be "System
Defaults". That goes for your Development and Distribution certificates, too. If any of them are incorrectly set to "Always Trust", that can apparently cause this problem.

So, in Keychain Access, click on the Apple Worldwide Developer Relations Certificate Authority certificate, select Get
Info. Then, expand the Trust settings, and for the combo box for "When using this certificate:", choose "System
Defaults".

Sigh: for those insistent on downvoting this answer, I am not claiming this to be the only solution for this problem. It's one solution. It may not work for you.
