On a Mac that logs on using AD credentials, you can get similar functionality by enabling the option "Create mobile account at login" in the Directory Utility that you use to configure AD connectivity for the MAC. When this option is enabled, the local mobile account is enable the first time the user logs on by using AD credentials.
Many times, no one thinks of this option until after the user has already logged on. In such a case, you need to log on as root and manually create the mobile account by using createmobileaccount. It is located in /System/Library/CoreServices/ManagedClient.app/Contents/Resources/.
