iphone - The identity certificate for com.xyz.profile.mdm could not be found?

Question

I've bumped into this issue while trying to install a MDM profile onto an ipad as the final part of OTA enrollment.

NSError:
Desc   : The identity certificate for com.xyz.profile.mdm1 could not be found.
US Desc: The identity certificate for com.xyz.profile.mdm1 could not be found.
Domain : MCMDMErrorDomain
Code   : 12005
Type   : MCFatalError
Params : (
"com.xyz.profile.mdm1"
)

Anyone have idea what piece of information i'm missing? This is when I try to install a MDM payload onto the IOS device after its completed the SCEP registration.

this is the payload I'm sending

If you are using self-signed ssl then,While generating self-signed ssl certificate in server side,generate identity.p12 certificate and this certificate you need to use in identity section of IPCU.

These few lines you can use to generate the idendtity.p12

//Creating the device Identity key and certificate request

openssl genrsa 2048 > identity.key
openssl req -new -key identity.key -out identity.csr


//Signing the identity key with the CA. 
//Give it a passphrase. You'll need to include that in the IPCU profile.

openssl x509 -req -days 365 -in identity.csr -CA cacert.crt -CAkey cakey.key -CAcreateserial -out identity.crt

openssl pkcs12 -export -out identity.p12 -inkey identity.key -in identity.crt -certfile cacert.crt
