Hello,
We use Apple's MDM service.
When we updated OpenSSL from 1.0.1e to 1.0.2r on SCEP server, profile cannot be installed to the iOS cleint.
After some investigation, we came up that iOS client ends up with following error when received PKCS#7 certificate from SCEP server during PKIOperation.
+----------------------------------------------
Could not retrieve issued certificate: NSError:
US Desc: The SCEP server returned an invalid response.
Domain : MCSCEPErrorDomain
Code : 22013
Type : MCFatalError
<Notice>: Cannot retrieve SCEP identity: NSError:
+----------------------------------------------
We did not change programs of SCEP server, though re-built modules with new OpenSSL library.
We use C++ for SCEP server modules.
Testing iOS client version is 12.0.1.
Does anyone know how to resolve this problem?
Kind regards,
