Action: New Mac OS X Lion to Active Directory binding.
Issue: Everytime I get the following error: authentication server encountered an error while attempting the requested operation.
Findings: Even if I’m connected to the internet, and using the Apple time server, the time on machines is not at all correct, which prevents the machines from binding to Windows Active Directory.
Solutions: Change the date and time to the correct values in your Apple machine and then restart the apple machine. Without a restart, this will not work.
