Novell ZENworks 10 Configuration Management with Support Pack 1 - 10.1 Migration
ERROR: "User Source is not defined or the user is not available in the user source. Use the ZENworks Control Center to create the user source and add the user zenworks.com/users"
This is fixed in version 10.1.2 - see KB 7001914 "ZENworks 10 Configuration Management 10.1.2" which can be found at https://www.novell.com/support
The root cause is that the Migration utility was trying to map the CN (Common Name) of user in eDirectory to the Display Name in AD (Active Directory)
