This feature requires version 1.7 or above.
SCEPman can be connected to Jamf as External CA. Via SCEPman's static interface and a challenge password enrolled devices will be able to obtain certificates. In addition, Jamf acts as SCEP Proxy for configuration profiles. So, Jamf proxies the communication between SCEPman and your devices.
Jamf integration of SCEPman can be easily enabled via the following app configurations:
SCEPman needs to be connected to the Jamf API to check the status of onboarded clients. This is used for the revocation of certificates. Please define the following app configuration parameters:
Therefore, please add an appropriate service account under "Jamf Pro User Accounts & Groups":
This account needs the following three read permissions under "Privileges" (section "Jamf Pro Server Objects"):
- Mobile Devices
Jamf Pro's Classic API supports Bearer Authentication since version 10.35.0. There is a setting to disable the previous authentication method, Basic Authentication, since version 10.36.0. A future Jamf version scheduled for August-December 2022 will remove support for Basic Authentication. SCEPman 2.0 and lower support only Basic Authentication for the Classic API, while SCEPman 2.1 and higher uses Bearer Authentication. In order to use Bearer Authentication, you must upgrade to SCEPman 2.1 or higher.
Open Jamf settings and choose "PKI Certificates" under "Global Management":
Switch to tab "Management Certificate Template", "External CA" and activate edit mode. Please enable Jamf as "SCEP Proxy for configuration profiles":
Please fill out the following fields and save the configuration:
When using an external CA, Jamf requires that you add the CA certificate so Jamf can compare whether the certificates are correctly signed. However, Jamf allows adding a CA certificate only, if you also add a signing certificate with a corresponding private key. Jamf uses this signing certificate to sign certificate requests send to SCEPman. However, SCEPman does not evaluate the signature on requests and accepts even unsigned requests (e.g. from Intune), because the request validity stems solely from using the right request challenge password configured in Jamf.
Hence, you may use any certificate you like signing certificate, for example you can generate a self-signed certificate with the following PowerShell command:
$cert = New-SelfSignedCertificate -Subject "CN=JAMF Signer Certificate for SCEPman" -CertStoreLocation "Cert:\CurrentUser\My" -NotAfter (Get-Date).AddYears(10)
$pfxBytes = $cert.Export([System.Security.Cryptography.X509Certificates.X509ContentType]::Pfx, "password")
Then click on "Change Signing and CA Certificates" in the External CA configuration of Jamf
In the wizard, upload the PFX file with the signing certificate to Jamf when it asks for it (Note: Pkcs#12 and PFX are synonyms). In the next steps, enter the password for the PFX file and confirm the selection of the signing certificate. In the tab "Upload CA Certificate", you must upload the SCEPman CA certificate. You can obtain the SCEPman CA certificate by clicking on the link "Get CACert" on the top right of the homepage of your SCEPman instance. Finally, confirm your changes.
