I have an odd issue. I am trying to export a certificate and key to a p12 file using the export feature in key chain. When it asks for the "login" password it does not take the password. The mac is running 10.11.1 (15B42)
I actually re-loaded the mac using the recovery image and get the same result. I was able to export from another mac just fine to a p12 file. The mac working is running 10.11 (15A284)
Does this sound like an OS X El Capitan keychain bug?
