Active Directory™ (AD)

is a distributed directory service that is a repository for user information. The NIOS appliance can authenticate admin accounts by verifying user names and passwords against Active Directory. In addition, the NIOS appliance queries the AD domain controller for the group membership information of the admin. The appliance matches the group names from the domain controller with the admin groups on its local database. It then authorizes services and grants the admin privileges, based upon the matching admin group on the appliance.
Figure 4.6 bookmark459 illustrates the Active Directory authentication process.

1 A user makes an HTTPS connection to the NIOS appliance and sends an account name and password.

1. The appliance checks the authentication policy to determine which authentication service to use. The authentication policy

specifies an AD authentication service.

1. The appliance sends an authentication request to the first domain controller in the AD server group. The appliance also

requests the group membership information of the admin.
4aThe appliance lets the user log in and applies the authorization profile.
The appliance grants all permissions specific to the administrator based on the group membership sent from the domain controller associated with the admin account. If there is no group membership information for the admin, the default group is assigned (if configured).
Authentication is successful. The domain controller successfully authenticates the admin user. The group membership information for the administrator is sent to the appliance. The first group in the list that matches the groups returned by the domain controller is assigned to the admin, along with the associated permissions after that admin logs in.
The appliance does not allow the user to log in.4b Authentication is unsuccessful. The domain controller sends back a deny
access result to the appliance. No group membership information is sent.

To configure NIOS to authenticate administrators using Active Directory domain controller groups, you must first configure user accounts on the domain controller. Then, on the NIOS appliance, do the following:

• Configure one or more AD authentication server group on the appliance and add AD domain controllers to the group. For information about configuring an AD authentication service group for admins, see Configuring an Active Directory Authentication Service Group bookmark460 bookmark460.
• If you configured admin groups on the AD controller, you must create those same groups on the NIOS appliance and specify their privileges and settings. Note that the admin group names must match those on the AD domain controller. You can specify a default group as well. The NIOS appliance assigns admins to the default group if none of the admin groups on the NIOS appliance match the admin groups on the AD domain controller or if there are no other admin groups configured. For information about configuring group permissions and privileges, see About Admin Groups .
• Add the newly configured Active Directory service to the list of authentication services in the admin policy, and add the admin group names as well. See Defining the Authentication Policy for more information about configuring an admin policy.
