Cannot Join OS X Lion to Active Directory 2003

Unable to join a mac mini recently upgraded to OS X Lion to Active Directory 2003 and get the following error: authentication server encountered an error whiles attempting the requested operation. 
 
I was able to re-join a OS X Lion server to AD 2003 as it was joined to the domain before upgrading to Lion. I had to rejoin as it did not communicate properly with AD after the upgrade.  

But, it was no issue. The mac mini that will not joining the domain, but just errors out. Usually, with Snow Leopard, when it would not join, it was something simple (time off, wrong username/password, etc…).  

Snow Leopard also gave much more helpful error messages that actually told you what the problem was. Lion only seems to give the generic error that is of no help.

Bound the domain through System Preferences rather than Directory Utility. System Preferences > Login Options > Network Account Server "Join" button. It successfully connected to server. example.com.fr (which is a 2003 Domain Controller)

Even though if u 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 AD. You can perform the below steps:

1. Change the date and time to the correct values (or within the acceptable threshold of your AD).

2. Restart the machine (will not work if you do not restart).

Your machines are now happily binding to AD.

If still faces a same problem we can say this: 10.7.2 really seems to have fixed all the stupid AD problems in the 2 previous releases. 

If you're having AD issues in Lion, stop everything and update if you're not using 10.7.2.

Hello Candice,

To resolve that issue, you will need to check the following.

  • You might be connected to the internet, but with the Apple time server, the time settings on machines may not at all be correct. That may be preventing the machines from binding to the Active Directory.  You will therefore need to do the following to resolve the issue:
  • You will need to change the date and time to the correct values, or just ensure that  they have been set within the acceptable threshold of your AD.
  • After that you can restart the machine.

Hope this helps.

Regards,

Carl
