Enable automatic authentication for
iOS
 devices

You can enable
iOS
 devices to authenticate automatically with domains and web services in your organization’s network. After you assign a single sign-on profile or sign-on extension profile, the user is prompted for a username and password the first time they try to access a secure domain that you specified. The login information is saved on the user’s device and used automatically when the user tries to access any of the secure domains specified in the profile. When the user changes the password, the user is prompted the next time they try to access a secure domain.
ou use a single sign-on extension profile to enable devices to authenticate automatically with domains and web services in your organization's network. You can specify settings for a custom extension or use the
Kerberos
 extension provided by
Apple
. 
If you want to use certificate-based authentication, create the necessary certificate profile.
  1. In the management console, on the menu bar, click
    Policies and Profiles > Networks and connections > Single sign-on extension
    .
  2. Click The Add icon.
  3. Type a name and description for the profile.
  4. In the
    Single sign-on extension type
     drop-down list, click
    Custom extension
     or
    Kerberos built-in extension
     provided by
    Apple
    .
