Troubleshooting Common Issues

Troubleshooting Active Directory Issues

Group Quota For An Active Directory User Does Not Work

Description

Group quota is defined for an Active Directory group; however, when a group

 

member consumes space, the actual usage of the group does not grow and the

 

group limitation is not enforced.

Cause

The NAS cluster solution quota enforcement is performed based on the UID and GID

 

of the file (UNIX) or the SID and the GSID of the primary group of the user (NTFS), if

 

defined.

 

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 setup the primary group for an Active Directory user:

 

1.

Open the Active Directory management.

 

2.

Right-click on the desired user.

 

3.

Select the Member Of tab.

 

 

The group you need must be listed.

 

4.

Click the group and then click the Set Primary Group button.

Now quotas takes effect for the user's group.

Active Directory Authentication

Description Cause

Workaround

A valid Active Directory user fails to authenticate.

Probable causes may be:

The user is trying to authenticate using an incorrect password.

The user is locked or disabled in Active Directory.

Active Directory domain controllers are offline or unreachable.

System clock and Active Directory clock are out of sync.

1.Check the NAS cluster solution system event log in the NAS Manager for errors.

2.Verify that the user is not disabled or locked in Active Directory.

3.Verify that domain controllers are online and reachable using the network.

4.Kerberos requires client/server clocks to be in sync. Verify the system time is in sync with the domain controller time and if required, configure the NTP setting of the system.

Troubleshooting Active Directory Configuration

Description

Unable to add Active Directory users and groups to CIFS shares.

Cause

Probable causes may be:

 

• Unable to ping the domain using FQDN.

 

DNS may not be configured.

 

NTP may not be configured.
