Configure MDM Server for iPhone - iphone

Question

It may seem to be asked several times, but I could not find answers to my doubts.
As one needs to setup an MDM server, what are the things that need to be available or installed on this server. Is there a specific configuration?
Is SCEP (which I think needs to be available on the server) required to setup MDM. If yes, how to go about with it.
When I set the Server URL inb the MDM config profile to any of the servers I have, the profile fails to install with the error in console as "The identity certificate for com.abc.mdm.mdm1 could not be found."
It'll be helpful if anyone could redirect me to the detailed steps to setup MDM server. I could not find any such thing in Apple's WWDC 2010 video.
Edit: Some more stuff I've tried
I'm trying to configure MDM server for iPhone and have tried the following steps till now.
I have installed a trial certificate from RapidSSL. When I open my site as https://example.com, I can see a lock at the address bar - hence I believe that the certificate is valid and working.
In iPCU, I create a credentials payload and select my certificate from the list.
In the MDM payload, when I try to select an Identity, the dropdown list is disabled with a message as Add credentials in the credentials payload.
In the credentials payload when I select any other certificate from the list - VeriSign for example - in the MDM payload I get the Identity dropdown list enabled and can select the configured credential, but this is an Invalid certificate.

Edit: Moved further more
With some hits here and there, I'm now able to get the 'Identity' field enabled. But when I try to install the profile, I get an error as 'Profile failed to install' with the message in console as

Edit: Continuing after a long break
Here's a summary of what I've done till now.
Configured a Windows 2008 server with an SSL certificate from a CA. ie. The server can be accessed as https://example.com
Hosted a .Net webservice that listens to PUT.
Generated an MDM certificate from the iOS Developer portal.
Generated a Push certificate from Apple. The topic is something like com.apple.mgmt.External.035e7xxxxx
Added the server certificate to the Credentials payload of iPCU. This was done by
- Exporting the server side SSL as a .pfx file
- Adding this file to the Windows Certificate store
- Selecting this certificate in the credentials payload.
I've hosted this profile on the server. When I download it on the device, I'm presented with Profile Installation on the device. When I install this profile, I end up with an error saying "The profile MDM could not be installed". On looking at the device logs, I found
<Notice>: (Error) MDM: Cannot Authenticate. Error: NSError:
Desc : A transaction with the server at “https://example.com” has failed with the status “400”
IMP: I noticed that the Push certificate generated says "This certificate was signed by an unknown authority". There's also no private key associated with it.
I suspect something wrong is selecting the certificate in the Credentials payload (Step 5).
Also when the Profile Installation screen is presented, I get "Not Verified" just below the the profile name.
Solved
For the "unknown authority" issue I installed Apple's Application Integration certificate.
I'm now able to execute the MDM commands.

Answer 1

You need just 3 things
1) mdm payload with mdm url starting with https://
2) certificate which you download using apple developer portal. This is detailed on apple site
3) Link this certificate (.p12) file in the identity section of the mdm payload
Your server needs to have the necessary ports open - this is also documented. The server needs to listen on PUT method and not GET or POST.
If you do above - you will see that your device sends the deviceToken, pushMagic etc.

Answer 2

First up, the 405 status from the server means that you are attempting to POST to a URL that does not accept the POST method. It has nothing to do with the certificates at this point. The certificate in MDM is only used for signing the MDM messages so anything that is put in there is unused if you are not signing your MDM messages from the device (I would recommend not signing your MDM messages while you are testing/setting up) which is configured using the 'Sign Messages' tick-box in the iPCU.
The general idea with MDM is that you tell the device to 'phone home' to the 'Server URL' configured in the configuration profile when it receives an MDM APNS message. You will either have to write or purchase the code that lives on this server to respond to the device and do the right thing. You can also configure the 'Check In' and 'Check Out' URLs to talk to different URLs and, therefore, different code components on the server to handle the different messages.
