If you're unable to bind your Mac to an Active Directory domain using a single part name, you need to fully qualify the server's domain name.
When using the steps below, substitute your domain name where you see 'w2003' used as an example.
Users & Groups preferences
Use these steps to update your domain name from Users & Groups preferences.
- Open System Preferences
- Click Users & Groups.
- Click Login Options.
- Click the lock icon, then enter your administrator name and password to authenticate.
- Click Join.
- Enter the domain name with the period appended (like 'w2003.') into the Server field.
- In the authentication field that appears, fill in the appropriate values, then click OK.
Use these steps to update your domain name from Directory Utility.
- Click the lock button to authenticate.
- Double click Active Directory.
- Enter the domain with the period appended (like 'w2003.').
- Click the Bind button.
- On the next panel, the Computer OU for where to put the computer record will be incorrect. It should look similar to this:
- Remove ",dc=" from the end of the entry so that Computer OU is similar to "CN=Computers,DC=w2003" then click OK.
Use these steps to modify the part name from the command line. For example, this Terminal command adds a period character to a domain named w2003:
sudo dsconfigad -add 'w2003.' -username <user> -password <password>
After you modify your part name, bind your server or client to the domain again by using these steps.
