What am I doing wrong - SSL Cert for WLC Generation

[roger perkin]

I am following this to the letter 

http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/109597-csr-chained-certificates-wlc-00.html

I have generated a CSR and got back a signed cert - however when I try to generate the final cert I get an error

When running this command 

openssl>pkcs12 -export -in All-certs.pem -inkey mykey.pem 
       -out All-certs.p12 -clcerts -passin pass:check123 
       -passout pass:check123

I get an error 

no certificate matches private key

pkcs12 error

Anyone know what I could be doing wrong?

Thanks

Roger

What version of OPENSSL did you use? I think you need to be 99 or lower.
