SCEP configuration (iOS user policy)

With the SCEP configuration you enable devices to request certificates from a Certificate Authority using the Simple Certificate Enrollment Protocol (SCEP).

Setting Description

The web address of the Certificate Authority server.

Use the variable %_SCEPPROXYURL_% to refer to the server URL that is configured on the SCEP tab of the Sophos setup page.

CA name A name that is understood by the Certificate Authority. The name can, for example, be used to distinguish between instances.

The name of the entity (for example person or device) that will receive the certificate.

You can use placeholders for user data or device properties.

The value that you enter (with placeholders replaced by the actual data) must be a valid X.500 name.

For example:

  • Enter CN=%_USERNAME_% to specify a user.
  • Enter CN=%_DEVPROP(SerialNumber)_% to specify an iPhone or iPad.

  • Uniform resource identifier: The fully qualified URL of the CA server.
Value of Subject Alternative Name
