I’m able to query device information, get list of profiles installed on the device

  • 0

I’m able to query device information, get list of profiles installed on the device etc, but am unable to install a profile onto the device.

I’ve configured a restrictions profile. When I host it on my server and download it via Safari, it installs. But when I encode it as base64 (as per MDM requirements) and try installing it, I get the following error.

DM: Attempting to perform MDM request: InstallProfile
Oct 10 10:25:32 iPhone-4 mdmd[516] <Notice>: (Error) MC: Failed to parse profile data. Error: NSError:
Desc   : Invalid Profile
US Desc: Invalid Profile
Domain : MCProfileErrorDomain
Code   : 1000
Type   : MCFatalError

Error: NSError:

Below is the Base64 encoded data of the profile I’m trying to install. I generated the below data based on the suggestions here and here

    The problem is solved. Just out of annoyance I removed the extra spaces between the XML tags of the .mobileConfig. See below…

    Changed

    <dict>
    <key>PayloadContent</key>
    <array>
        <dict>
            <key>PayloadDescription</key>
            <string></string>
            <key>PayloadDisplayName</key>
            <string>Restrictions</string>
..........
</dict>

    to 

    <dict><key>PayloadContent</key><array><dict><key>PayloadDescription</key><string></string><key>PayloadDisplayName</key><string>Restrictions</string>..........</dict>

    I used this site to encode it into base64. (for testing only)

    For future viewers, you need to start from the <dict> tag
