iOS 编辑

To manage iOS devices in XenMobile Server, you set up an Apple Push Notification service (APNs) certificate from Apple. For information, see APNs certificates.

Enrollment profiles determine whether iOS devices enroll in MDM+MAM, with the option for users to opt out of MDM. XenMobile Server supports the following authentication types for iOS devices in MDM+MAM. For information, see the articles under Certificates and authentication.

• Domain
• Domain plus security token
• Client certificate
• Client certificate plus domain

Requirements for trusted certificates in iOS 13:

Apple has new requirements for TLS server certificates. Verify that all certificates follow the new Apple requirements. See the Apple publication, https://support.apple.com/en-us/HT210176. For help with managing certificates, see Uploading certificates in XenMobile Server.

For supported operating systems, see Supported device operating systems.

iOS 14 compatibility

XenMobile Server and Citrix mobile apps are compatible with iOS 14, but don’t currently support the new iOS 14 features.

For supervised iOS devices, you can delay software upgrades for up to 90 days. In the Restrictions device policy for iOS, use these settings:

• Force delayed software updates
• Enforced software update delay

See iOS settings. Those settings aren’t available for devices in user enrollment mode or unsupervised (full MDM) mode.

Apple host names that must remain open

Some Apple host names must remain open to ensure proper operation of iOS, macOS, and Apple App Store. Blocking those host names can affect the installation, update, and proper operation of the following: iOS, iOS apps, MDM operation, and device and app enrollment. For more information, see https://support.apple.com/en-us/HT201999.

Supported enrollment methods

You specify how to manage iOS devices in enrollment profiles. You can choose device enrollment or no MDM enrollment.

To configure enrollment settings for iOS devices, go to Configure > Enrollment Profiles > iOS.

The following table lists which enrollment methods XenMobile Server supports for iOS devices:

Apple has device enrollment programs for business and education accounts. For business accounts, you enroll in the Apple Deployment Program to use the Apple Deployment Program for device enrollment and management in XenMobile Server. That program is for iOS and macOS devices. See Deploy devices through Apple Deployment Program.

For education accounts, you create an Apple School Manager account. Apple School Manager unifies the Deployment Program and volume purchase. Apple School Manager is a type of Education Apple Deployment Program. See Integrate with Apple Education features.

You can use the Apple Deployment Program to bulk enroll iOS and macOS devices. You can purchase those devices directly from Apple, a participating Apple Authorized Reseller, or a carrier. Whether you purchase iOS devices directly from Apple, you can use the Apple Configurator to enroll those devices. See Bulk enrollment of Apple devices.

Security actions

iOS supports the following security actions. For a description of each security action, see Security actions.

Lock iOS devices

You can lock a lost iOS device with an accompanying display of a message and phone number that displays on the device lock screen.

To display a message and phone number on a locked device, set the Passcode policy to true in the XenMobile Server console. Alternatively, users can enable the passcode on the device manually.

1. Click Manage > Devices. The Devices page appears.

   

2. Select the iOS device you want to lock.

   Select the check box next to a device to show the options menu above the device list. Click anywhere else in the list to show the options menu on the right side of the listing.

   

   

3. In the options menu, click Secure. The Security Actions dialog box appears.

   

4. Click Lock. The Security Actions confirmation dialog box displays.

   

5. Optionally, type a message and phone number that appears on the lock screen of the device.

   iOS appends the words “Lost iPad” to what you type in the Message field.

   If you leave the Message field empty and provide a phone number, Apple displays the message “Call owner” on the device lock screen.

6. Click Lock Device.

Put iOS devices in Lost Mode

The XenMobile Server Lost Mode device property puts an iOS device in Lost Mode. Unlike Apple Managed Lost Mode, XenMobile Server Lost Mode doesn’t require a user to perform either of the following actions to enable locating their device: Configure the Find My iPhone/iPad setting or enable the Location Services for Citrix Secure Hub.

In XenMobile Server Lost Mode, only XenMobile Server can unlock the device. (In contrast, if you use the XenMobile Server device lock feature, users can unlock the device directly by using a PIN code that you provide.

To enable or disable lost mode: Go to Manage > Devices, choose a supervised iOS device, and then click Secure. Then, click Enable Lost Mode or Disable Lost Mode.

If you click Enable Lost Mode, type information to appear on the device when it’s in lost mode.

Use any of the following methods to check Lost Mode status:

• In the Security Actions window, verify if the button is Disable Lost Mode.
• From Manage > Devices, on the General tab under Security, see the last Enable Lost Mode or Disable Lost Mode action.

• From Manage > Devices, on the Properties tab, verify that the value of the MDM lost mode enabled setting is correct.

If you enable XenMobile Server Lost Mode on an iOS device, the XenMobile Server console also changes as follows:

• In Configure > Actions, the Actions list doesn’t include these automated actions: Revoke the device, Selectively wipe the device, and Completely wipe the device.
• In Manage > Devices, the Security Actions list no longer includes the Revoke and Selective Wipe device actions. You can still use a security action to perform a Full Wipe action, as needed.

iOS appends the words “Lost iPad” to what you type in the Message in the Security Actions screen.

If you leave the Message empty and provide a phone number, Apple shows the message “Call owner” on the device lock screen.

Bypass an iOS activation lock

Activation Lock is a feature of Find My iPhone/iPad that prevents reactivation of a lost or stolen supervised device. Activation Lock requires the user Apple ID and password before anyone can perform these actions: Turn off Find My iPhone/iPad, erase the device, or reactivate the device. For the devices that your organization owns, bypassing an Activation Lock is necessary to, for example, reset or reallocate devices.

To enable Activation Lock, you configure and deploy the XenMobile Server MDM Options device policy. You can then manage a device from the XenMobile Server console without the Apple credentials of the user. To bypass the Apple credential requirement of an Activation Lock, issue the Activation Lock Bypass security action from the XenMobile Server console.

For example, if the user returns a lost phone or to set up the device before or after a Full Wipe: When the phone prompts for the Apple App Store account credential, you can bypass that step by issuing the Activation Lock Bypass security action from the XenMobile Server console.

Device requirements for activation lock bypass

• Supervised through Apple Configurator or Apple Deployment Program
• Configured with an iCloud account
• Find My iPhone/iPad enabled
• Enrolled in XenMobile Server
• MDM Options device policy, with activation lock enabled, is deployed to devices

To bypass an activation lock before issuing a Full Wipe of a device:

1. Go to Manage > Devices, select the device, click Secure, and then click Activation Lock Bypass.
2. Wipe the device. The activation lock screen doesn’t appear during device setup.

To bypass an activation lock after issuing a Full Wipe of a device:

1. Reset or wipe the device. The activation lock screen appears during device setup.
2. Go to Manage > Devices, select the device, click Secure, and then click Activation Lock Bypass.
3. Tap the Back button on the device. The home screen appears.

Keep in mind the following:

• Advise your users not to turn off Find My iPhone/iPad. Don’t perform a full wipe from the device. In either of those cases, the user is prompted to enter the iCloud account password. After account validation, the user won’t see an Activate iPhone/iPad screen after erasing all content and settings.
• For a device with a generated Activation lock bypass code and with the Activation lock enabled: If you can’t bypass the Activate iPhone/iPad page after a Full Wipe, there is no need to delete the device from XenMobile Server. Either you or the user can contact Apple support to unblock the device directly.
• During a hardware inventory, XenMobile Server queries a device for an Activation lock bypass code. If a bypass code is available, the device sends it to XenMobile Server. Then, to remove the bypass code from the device, send the Activation Lock Bypass security action from the XenMobile Server console. At that point, XenMobile Server and Apple have the bypass code required to unblock the device.
• The Activation Lock Bypass security action relies on the availability of an Apple service. If the action doesn’t work, you can unblock a device as follows. On the device, manually enter the credentials of the iCloud account. Or, leave the user name field empty and type the bypass code in the password field. To look up the bypass code, go to Manage > Devices, select the device, click Edit, and click Properties. The Activation lock bypass code is under Security information.
