Associate JSON configuration to devices(old steps)
The last step in the portal is to associate the created JSON configuration to the devices. To do that, follow the steps given below:
- Login to your Zero-touch portal with the Google account associated with your corporate e-mail.
- You can set the configuration which you have created as default.
- Click on Configurations on the left pane and under Default Configuration, select the configuration, which is to be automatically applied to the added devices.
Assigning Zero-touch configurations to devices individually
If you want to maintain different configurations for devices, you need not set a default configuration. Instead you can manually assign configuration to devices. You can do that by assigning configuration to devices in the Zero-touch console or you can do so by assigning a CSV.
- To associate the MDM configuration to multiple devices,Click on Devices in the left navigation panel, the ellipsis (three dots) icon present on the right and select Upload batch configuration.
- Create a CSV based on the specifications given in Device configuration CSV file format and add it by clicking on Upload. All the devices listed in the CSV, are assigned the specified MDM configuration.
Device configuration CSV file format
You can apply individual MDM configurations in a CSV. To know more about the fields in CSV follow the table below:
|modemtype||The parameter to be used for identification. The parameter is always IMEI and it should always be in uppercase.||IMEI|
|modemid||The value corresponding to the specified modemtype parameter, which is always the IMEI number.||150520043826120|
|manufacturer||The name of the device maker/manufacturer(Original Equipment Manufacturer: OEM).|
|profiletype||The objective of assigning the profile to the device, which in this case is always zero touch enrollment. The parameter is always ZERO_TOUCH and it should always be in uppercase||ZERO_TOUCH|
|profileid||The ID corresponding to the MDM configuration, to be assigned to the devices. To view the configuration ID, select Configurations from the left pane in the zero touch portal. The number sequence present under ID is the configuration ID for the particular configuration.||036180|
Link Zero-touch with Android for Work(updated users)
If you have already set up a Zero-touch portal using JSON steps, you can link it with Android for Work in later versions of Mobile Device Manager Plus. Configure Android for Work and link it as mentioned above. If Android for Work is configured, you can link it with Zero-touch. Go to Enrollment -> Zero-touch enrollment -> Settings -> Launch Zero-touch portal.
Device activation can be performed either by user or admin based on user assignment.
When Zero-touch devices are activated for the first time, they will be automatically enrolled into MDM. The MDM app will be installed during activation. Here is how the process looks on the device:
- On activation, the welcome screen appears.
- Connect to a WIFI network to continue setting up Zero-touch.
- The images below will convey the stages of device activation.
- The ME MDM app will be installed automatically after initialization. If the admin has assigned users, the device is assigned to respective user, or else the user can assign themselves using Active Directory credentials.
It is mandatory to connect to the Internet during the activation process, to enroll the device with MDM. So, the ME MDM app gets installed and enrollment is performed. When there is no internet, the device enrollment does not happen. Even if we activate without the Internet, the device gets enrolled after connecting to the Internet.
The devices get enrolled with MDM through Android Enterprise Zero Touch enrollment, either during device activation (in case of new devices) or factory reset (in case of devices in use). Now the device must be assigned to a user.After the devices are activated, the final step in completing enrollment is user assignment. You can choose to assign users to devices manually or automate it by allowing users to complete the assignment by entering their directory service credentials.We will guide you more about it in detail below.
You can assign users two ways. You can choose to assign users manually after a device is activated; or you can let the users activate devices themselves and authenticate using their directory credentials. You can configure the settings from here: Enrollment -> Zero-touch Enrollment -> Settings -> Device Activation
Assign users manually
You can additionally add the devices to multiple groups to automate the distribution of profiles, apps and documents to devices. To do that, follow the steps given below:
- On the MDM server, click on Enrollment from the top menu.
- Select Zero Touch Enrollment from the left pane.
- Here all the devices enrolled via zero touch enrollment but yet to be assigned users are listed.
- You can assign users on a device-to-device basis, by clicking on the Assign User option present under Action.
- You can also assign users in bulk, by click on the Assign Users button, present above the table and uploading a CSV file, based on the specifications given here.
- When devices are purchased in bulk, the reseller will provide the serial numbers & IMEI numbers along with the invoice. You can pre-assign users using these identifiers with the help of a sample CSV. The serial numbers or IMEI numbers should be inserted in a sample CSV which can be uploaded to Assign Users. When the devices are activated, they will automatically get assigned to the users.
Sample CSV Format
- The fields Serial Number, User Name, Email Address and Group Name are mandatory. All the other fields are optional. Ensure the specified group name is already created in the MDM server. If values are not provided, default values will be taken.
- The default values for various non-mandatory fields are:
Domain Name -- MDM
Owned By -- Corporate
- If multiple groups are specified, the group names must be separated with a slash (/)
- The first line of the CSV is the column header and the columns can be in any order.
- Blank column values should be comma separated.
- If the column value contains comma, it should be specified within quotes.
Automate User Assignment
The user assignment can be automated by enabling the users to enter their directory service credentials upon device activation
- Select User for the option Device to be activated by.
- If you haven't configured a directory service, you'll be prompted to configure one. Mobile Device Manager Plus supports multiple directory services:
- Active Directory
- Azure AD
- G Suite
- You can optionally also select a Group to which the devices will be added upon enrollment. This will help automate the distribution of apps, documents and profiles to devices.
Dissociating Zero-touch portal
When you no longer need Zero-touch enrollment for your enterprise, you can dissociate it either by
- Removing Android for Work-This will remove the Enterprise Default configurations and the device will be unmanaged on device activation.You can do it by un-linking the enterprise account in the portal by clicking Enrollment -> Zero-touch Enrollment -> Settings -> Launch Zero-touch portal.
After un-linking the account, you can click Remove Android for Work in the portal and account gets removed.On removing the account, the configurations will be deleted.
- Deleting the MDM configurations(old users)-Choose the configuration which has to be deleted.This will remove the MDM configuration associated with the devices and on reset, it gets removed from MDM management. If you delete the default configuration, then it gets applied to all the devices.
When you remove Android for Work, you cannot perform silent installation of apps.
