Hello, I am Sergio Sánchez, administrator of NumbuX. We are developing our own MDM. We are already granted as a MDM Vendor. We need to issue the APNs certificate for our MDM for the first time in the Push Certificate portal (identity.apple.com). We are having the error: “invalid signing request” when we upload the signed CSR to identity.apple.com. That is because we do not have the External UUID. Could you please let us know what is our External UUID? Without that, we cannot upload it successfully. We have already compared different signed CSR from other MDM Vendors and all have included the External UUID in the CSR. Please, do not send links, there is not way for us to know our External UUID because it is the first time that we try to issue this APNs. After the first time, we do not need your assitance. Please, let us know our External UUID. Thank you. Kind regards.

Nuestra cuenta está aprobada como MDM Vendor y necesitamos emitir por primera vez el certificado APNs para MDM en el portal de Push Certificates. Procedimiento seguido Primero hemos descargado desde nuestra cuenta de Apple Developer el certificado de MDM Vendor y lo hemos instalado en el ordenador. Esto lo hemos hecho para que, al lanzar la instrucción de OpenSSL, se pueda utilizar el UUID gestionado por Apple y así generar el CSR de forma correcta. La instrucción que estamos ejecutando es la siguiente: openssl req -new -newkey rsa:2048 -nodes -keyout mdm_private.key -out mdm.csr -subj "/O=Numbux/OU=MDM/CN=com.apple.mgmt.External." El CSR resultante es puro (no está firmado ni empaquetado) y está generado con RSA 2048 y SHA256. Sin embargo, al subirlo al portal de Push Certificates, seguimos recibiendo el error “invalid signing request”. Solicitud Dado que es nuestra primera emisión, entendemos que necesitamos el External UUID asignado por Apple a nuestra organización, porque veo que el problema se deriva de una incorrecto UUID que se está generando en el comando OpenSSL. ¿Podríais confirmarnos cuál es ese valor para poder completar el CSR y así emitir correctamente el certificado APNs MDM? He llamado a los números 900 812 703 y al 900 812 468 y he escrito al soporte de developer. NADIE ES CAPAZ DE DARMELO. Sin el external UUID no puedo crear el APN para mi MDM. Alguien me puede ayudar? No me mandeis links ni posibles números que llamar porque ya lo he hecho.

Hello, I have an Apple Developer Enterprise account, and Apple Support has already enabled MDM for my account. I successfully downloaded and installed my MDM Vendor Certificate (it shows up in Keychain as MDM Vendor: [My Company Name] with its private key). Here’s what I’ve done so far: Exported the Vendor Certificate + private key as a .p12, then converted to .pem and .key using OpenSSL. Generated an unsigned CSR with CN=com.apple.mgmt.External. using OpenSSL. Attempted to sign the CSR using: my Vendor certificate the Vendor private key Apple Worldwide Developer Relations (WWDR) intermediate certificate OpenSSL smime -sign command with DER output Problem: Every time I try to upload the vendor-signed CSR to the Apple Push Certificates Portal, I get an error (CSR rejected). Sometimes OpenSSL even fails with “unable to load certificates” depending on how the WWDR certificate is included. My Questions: What is the correct OpenSSL command and certificate chain Apple expects for signing the CSR? Do I need to include any additional intermediates besides WWDR? Is there an official Apple reference example for generating the vendor-signed CSR that the Push Certificates Portal will accept? Any guidance from the community (or someone who has successfully done this end-to-end) would be greatly appreciated. Thank you, Sergio Sanchez

Hello, I am thinking of developing a parental control app but I do not know if I need to request the api for using "Time Screen API". In positive case, where it should be? Is there anyway to use this for educational centers? Not just for families? Kind regards.
