Create Active Directory Server elements

The Active Directory Server element contains both the user database and authentication service options for using a Microsoft Active Directory server to store and authenticate users.

The settings in the Active Directory Server element can optionally include an account that the Management Server and NGFW Engines use to connect to query the directory. The user account must exist in the Active Directory Server’s user database. Make sure the account you use has the permissions to manage other user accounts. The NGFW Engines and Management Server can also connect to query the directory without a user name and password if the Active Directory Server allows anonymous bind requests.

There are also values for some attributes that the Management Server and NGFW Engines look for in the directory. We recommend that you do not use special characters or accented letters in the Distinguished Names or user ID attributes. Currently, Active Directory has a limit of 160 characters for the Base DN, 24 characters for a UID (user ID) and 64 characters for the OU (organizational unit).

Steps

Select Configuration, then browse to User Authentication.
Right-click Servers, then select New > Active Directory Server.
On the General tab, configure the general settings.
(Optional) On the Advanced tab, add one or more secondary IP addresses for the server.
These IP addresses are included when the Active Directory Server element is used in rules, but SMC components never use the addresses when initiating contact with the server.
(Optional) If you want to enable the Integrated User ID Service on an NGFW Engine and use the Active Directory Server in the Integrated User ID Service configuration to monitor logon information from Domain Controllers or Exchange Servers, configure the settings for the Domain Controllers and Exchange Servers on the Monitored Servers tab.

Note: The Integrated User ID Service is primarily meant for demonstration purposes and proof-of-concept testing of user identification services.

Note: The NGFW Engine uses the BIND user that is configured in the Active Directory Server element properties to monitor logon events.
(Optional) If you want the Active Directory Server to be monitored by the Log Server, configure the monitoring settings on the Monitoring tab.
Click OK.

Active Directory Server Properties dialog box

Use this dialog box to define Active Directory Server properties.

Option	Definition
General tab
Name	The name of the element.
IP Address	Specifies the server IP address. IPv4 addresses, IPv6 addresses, and fully qualified domain names (FQDNs) are supported. You can enter only one IPv4, IPv6 or FQDN as the IP address.
Resolve	Automatically resolves the IP address of the server.
Location	A Location is needed if NAT is applied between a Firewall or Management Server and the Active Directory server.
Contact Addresses	Default — Used by default whenever a component that belongs to another Location connects to this server. Exceptions — Opens the Exceptions dialog box.
LDAP Protocol	Specifies the LDAP protocol that is used for the LDAP connection. LDAP — The LDAP is used without encryption. LDAPS — The LDAPS protocol is used for encryption. Start TLS — Start TLS is used for encryption.
LDAP Port (Optional)	Specifies the port number if the server communicates on a port other than the default TCP 389 port. The predefined Firewall Template allows the engines to connect to the default port. If you change to a custom port, you must add an Access rule to allow the traffic.
Timeout	Specifies the time (in seconds) that SMC components wait for the server to reply.
TLS Profile (When the LDAP Protocol is LDAPS or Start TLS)	Specifies the settings for cryptography, trusted certificate authorities, and the TLS version used in TLS-protected traffic. Click Select to select a TLS Profile element.
TLS Server Identity (When the LDAP Protocol is LDAPS or Start TLS)	Determines how the identity of the LDAP server is verified. Edit — Opens the TLS Server Identity dialog box. Remove — Removes the configured TLS Server Identify.
Base DN	Enter the LDAP tree under which the authenticating users accounts are stored. Example: (DNS-based tree) dc=example,dc=com Example: ("O-based" tree used, for example, in Novell eDirectory) ou=astronauts,o=government,st=Florida,c=US
Anonymous (Optional)	When selected, allows NGFW Engines and Management Servers to connect to the LDAP server without a user name and password. When the option is selected, the Bind User ID and Bind Password options are not available.
Bind User ID	Define the Distinguished Name of the User ID that the Firewalls and Management Servers use to connect to the server. This user account must exist in the user database. Make sure the account you use has the permissions to manage other user accounts. Example: (DNS-based tree) uid=ExampleOrganization,ou=Administrators,dc=example,dc=com Example: ("O-based" tree used, for example, in Novell eDirectory) uid=ExampleOrganization,ou=Administrators,ou=astronauts, o=government,st=Florida,c=US

If your Active Directory server has Active Directory server user object classes that are not defined in the SMC by default, you must add those object classes to the Active Directory Server Object classes in the server properties. This way, the existing classes on the LDAP server can also be used for authentication.
Add	Adds the user objectclass name to the list of available classes.
Remove	Removes the user objectclass name from the list of available classes.
Group ObjectClass	Allows you to add group objectclasses manually. If your Active Directory server has Active Directory group object classes that are not defined in the SMC by default, you must add those object classes to the Active Directory Object classes in the server properties. This way, the existing classes on the Active Directory server can also be used for authentication.
Add	Adds the group objectclass name to the list of available classes.
Remove	Removes the group objectclass name to the list of available classes.

Option	Definition
Attributes tab
Schema	Standard — Select if you are using the external LDAP directory server’s standard schema files. Updated — Select if you have extended the schema file to include SMC-specific attributes.

Group Member	Specifies the name that the server uses for the Group Member Attribute. The default value is member for standard schema, and sgMember for updated schema.
Authentication (Updated Schema only)	Specifies the Authentication Attribute for storing the authentication method information. The default value is sgauth.
Display Name (Updated Schema only)	Specifies the name that the server uses for the Display Name attribute.
