Administrator Guide

For Active Directory users, the Primary Group setting is not mandatory, and if not defined, the used space is
not accounted to any group. For group quota to be effective with Active Directory users, their primary group
must be assigned.
Workaround To set up the primary group for an Active Directory user:
1. Open the Active Directory management.
2. Right-click on the user and select Properties.
3. Select the Member Of tab.
4. The group you need must be listed. Click the group and then click Set Primary Group.
Now quotas takes effect for the user's group.
Active Directory User Authentication Fails
Description A valid Active Directory user fails to authenticate.
Cause Probable causes might be:
• The user is trying to authenticate using an incorrect password.
• The user is locked or disabled in Active Directory.
• The Active Directory domain controllers are offline or unreachable.
• The FluidFS cluster system time and Active Directory clock are out of sync.
Workaround
1. Check the FluidFS cluster Event Log for errors.
2. Verify that the user is not disabled or locked in Active Directory.
3. Verify that the domain controllers are online and reachable using the network.
4. The FluidFS cluster and Active Directory server must use a common source of time. Configure NTP and
verify the system time is in sync with the domain controller time.
Active Directory Configuration Issues
Description
Unable to add Active Directory users and groups to SMB shares.
Cause Probable causes might be:
• Unable to ping the domain using a FQDN.
• DNS might not be configured.
• NTP might not be configured.
Workaround When configuring the FluidFS cluster to connect to an Active Directory domain:
1. Ensure that you use a FQDN and not the NetBIOS name of the domain or IP address of the domain
controller.
2. Ensure that the user has permissions to add systems to the domain.
3. Use the correct password.
4. Configure DNS.
5. The FluidFS cluster and Active Directory server must use a common source of time. Configure NTP and
verify the system time is in sync with the domain controller time.
6. If multiple NAS appliances are used, ensure that you set different NetBIOS names. The system defaults to
SMB Storage as the name.
