The enrollment proﬁle can be installed through IPCU directly, or through

an IPCU-created proﬁle pulled off a web link, or by another process

hosted on the MDM server.

Once the proﬁle is installed, the device sends the Authenticate

message, then in a separate connection, the TokenUpdate message.

The ﬁrst step is the device authenticating itself to the server. It’s not so

much a secure authentication as it is a simple identiﬁcation, but it

provides the server a chance, based on the Topic and UDID provided, to

accept or reject the enrollment request. This can be used to prevent just

anyone from enrolling with the corporate MDM server. (additional steps

at a more user-friendly level, such as web-based authentication panels

with real usernames/passwords, are also possible, and can be used

prior to creating an enrollment proﬁle).

The data is presented to the server over HTTP (perhaps SSL-

encryped), using PUT, to the URL speciﬁed in the enrollment proﬁle’s

“Check In” ﬁeld. The data itself is an Apple Property List (.plist) ﬁle,

XML formatted. [key elements of the data are highlighted here in red]
