Error when trying to obtain a certificate: The specified item could not be found in the keychain

Question

I was having a problem with codesigning my apps, so I deleted all the keys from the keychain. Then I went to Certificate Assistant => Request a certificate from a Certif

Answer 1

This was happening to me I noticed that the menu option for creating the certificate request had changed from

Request a Certificate from a Certificate Authority...

to

Request a Certificate from a Certificate Authority with "My Name"...

I'm on a domain at work so I logged out, logged in and out as another user, then logged in again. After that the menu appeared as expected and this error went away
