Windows Domain and Active Directory

The ReadyNAS failed to authenticate with the domain controller. What should I do?

In most cases, this comes down to a DNS problem. You'll need to make sure that the ReadyNAS is configured to resolve DNS from a properly configured DNS server. The easiest way is to run the DNS service on the domain controller. For NT4-style domains, make sure you are joining using an account with proper credentials for joining the domain.

How many domain users can the ReadyNAS handle?

The ReadyNAS can handle up to 30,000 user + computer accounts, and up to 30,000 group accounts. Please do note however that the web-based FrontView management utility will behave slowly when there are more than a couple thousand domain users. We are hoping to have a firmware update in the future to resolve this problem.

Our domain user(s) can not login to the ReadyNAS. What should I do?

1. Make sure the ReadyNAS has successfully joined the domain.
2. Make sure the login credential is correct.
3. Make sure the user is logged into the domain on the client PC.

How do I change the file and folder permission on the ReadyNAS that is attached to domain controller?

You can use Windows ACLs to do this -- right-click on a file, select Properties, then the Security tab. From there, you can set the permissions as desired. Most Windows operating systems will have this feature. Some, such as Windows XP Home, do not. To get the Security option to show under properties, you may need to uncheck the "simple file sharing" option in the Folder Options/View menu.

How do I access the user home folder on ReadyNAS?

You can access the user home shares over CIFS or AFP.

Can I change the name of the ReadyNAS after it has already joined an Active Directory Domain?

Yes, but you will need to rejoin the domain.

How come data copied to the ReadyNAS does not maintain all the ACL's permissions?

Windows does not preserve ACLs when dragging files over the network, regardless of whether the target is a ReadyNAS or a Windows server. To preserve ACLs, you can use xcopy /o from the command prompt.

Why am I not able to create users in the ReadyNAS after joining Domain?

All account management is handled on the domain controller.

Under the Domain security mode, each time users access the ReadyNAS, it keeps asking for a login name and password. How can this be prevented?

It's likely the system clocks on the ReadyNAS and the domain controller are not sync'd. It is recommended that a common NTP server be used to keep the clocks in sync.

After joining ReadyNAS to a Domain Controller, the ReadyNAS does not list users and groups under account tab. How do I fix this?

Make sure your DNS and the ADS realm address settings are correct.
