Mac server MDM profile manager enrollment problem I use mac os server to active the Profile Manager and Open Directory.
And I want to enroll our devices to the server 

Why My ipad and iphone always get the error:

Profile Installation Failed
The SCEP server configuration is not supported!


[
If I use the server to enroll

Profile installation failed.
Could not be installed due to an unexpected error.
&lt;NSOSStatusErrorDomain:-1096&gt;
