Hi
I'm trying to add CA certificates into my organization, but always have the same result: " Error: The certificate that you are uploading doesn't match the generated certificate signing request. "

I get the certificate from outside webserver, and download it from Mozilla browser. When I view that certificate, I can see CN, O, L, ST, C, but can't see Organizational Unit (OU)
I follow this steps:
  - Setup - Security Controls - Certificate and Key Management - Create CA Signed certificate
  - put into the fields the info that I can see in downloaded certificate

After that, I try to upload downloaded signed certificate into salesforce, but y get error with signin request.

Can anyone help me?

Thanks
